LASER SAFETY
VISIBLE AND/OR INVISIBLE LASER RADIATION
CAUTION: The Jewel Laser is a Class 4 OEM laser. Its output beam is, by
definition, a safety and fire hazard. Precautions must be taken to prevent
accidental exposure to both direct and reflected beams.
Precautions for Safe Operation of Class 4 OEM Lasers:
DO NOT remove the protective covers from the Laser Head. No user serviceable
components are inside. Exposure to laser radiation when covers removed.
Avoid looking directly at the laser output beam.
Do not wear reflective jewelry while using the laser, as it might cause inadvertent
hazardous reflections.
Use protective eyewear at all times. Consult the ANSI, ACGIH, or OSHA standards listed
at the end of this section for guidance on goggles and safety matters.
Operate the laser at the lowest possible beam intensity, given the requirements of the
intended application.
Increase the beam diameter wherever possible to reduce beam intensity and thus reduce
the hazard.
Avoid blocking the laser beam with any part of the body.
Use an IR detector or energy detector to verify that the laser beam is off, before working in
front of the laser.
Establish a controlled access area for laser operation. Limit access to those trained in the
principles of laser safety.
Maintain a high ambient light level in the laser operation area so the eye pupil remains
constricted, thus reducing the possibility of hazardous exposure.
Post prominent warning signs near the laser operation area.
Provide enclosures for the beam path whenever possible.
Set up an energy absorber to capture the laser beam, preventing unnecessary reflections
or scattering.

Jewel Manual v1.6 | Quantum Composers Page 7
CAUTION: Use of controls, adjustments or performance of procedures other
than those specified in this Operation Manual may result in hazardous
radiation exposure.
Follow the instructions within this manual carefully to ensure the safe operation of your
laser. At all times during laser operation, maintenance, or servicing, avoid unnecessary
exposure to laser or collateral radiation that exceeds the accessible emission limits listed in
"Performance Standards for Laser Products," United States Code of Federal Regulations,
21 CFR 1040.10(d). This information is also available in EN60825-1:1994, Section 8.2,
titled “Measurements of Laser Radiation for Determining Classification.”
Preventative Maintenance for Safety: Preventative maintenance is required to ensure the
laser remains in compliance with Center for Devices and Radiological Health (CDRH)
Regulations and European Norm (EN) requirements. This laser product complies with Title
21 of the United States Code of Federal Regulations, Chapter 1, Subchapter J, Parts
1040.10, as applicable, and with EN60825-1:1994, Part 1 for a Class 4 laser, as applicable.
To maintain compliance, verify the operation of all features listed below, either annually or
whenever the product has been subjected to adverse environmental conditions, which may
have affected these features and functions.
oVerify that removing the remote interlock connector prevents laser operation. This
connector is located on the end cap of the laser.
oVerify that the laser will operate only with the key switch in the ON position and the
key can only be removed when the switch is in the OFF position.
oVerify that a time delay exists between turning on the Key Switch and the start of
laser firing. The time delay must be long enough to allow action to be taken to avoid
exposure to laser radiation.
Please follow all local jurisdictional safety requirements for your area.
ELECTRICAL SAFETY
CAUTION: Both the Laser Optics Assembly and Laser Power Supply contain
electrical circuits operating at lethal voltage and current levels. Always
unplug the system Mains connection and wait at least one (1) minute to allow
capacitors to discharge before servicing any part of the laser system.
Consult with the Quantum Composers if repair of the laser electronics is required. Only those
trained in high voltage, high current electronics, and who understand the laser circuitry, should be
allowed to service and repair the laser electronics. If any such action is required, it is
recommended that you contact the Quantum Composers for details.

3. SYSTEM OVERVIEW

Page 12 Jewel Manual v1.6 | Quantum Composers
JEWEL LASER DESCRIPTION
The Jewel is a conductively-cooled 1064/532/355/266nm diode pump laser with output energy
pulses up to 15mJ and rep rates up to 20Hz. It is a self-contained laser head, including the diode
and Q-switch drivers.
LASER FEATURES
The laser features (Figure 10 and Figure 11) are indicated below.
Figure 10 Jewel Connection Panel

Jewel Manual v1.6 | Quantum Composers Page 13
Figure 11 - Laser Features
1. The laser resonator is a highly efficient diode pumped laser (20Hz less than 5W) with a
fundamental output wavelength of 1064nm. The monolithic structure is machined from a
single block of stress-relieved aircraft grade aluminum. Resonator mirrors are hard-
mounted to the machined resonator bench resulting in an extremely stiff, rugged resonator
which is much less sensitive to misalignment then other laser resonators.
2. Systems w/ output harmonics, 532/355/266nm, have an attached nonlinear optics module
(NLO). The 1064nm output of the laser enters the integral nonlinear module. Harmonic
generation is performed using non-linear crystal(s). The crystal temperature is tightly
regulated by mounting the crystals inside a temperature controlled oven assembly. The
output is collinear, with all wavelengths exiting the same aperture.
3. An optional dichroic module can be attached to “scrape” residual wavelengths from the
output beams allowing single wavelength output.

UNPACKING LASER
The laser has been carefully packaged for shipment. If the container arrives damaged in any way,
please contact the shipper's agent to be present for the unpacking. Inspect each unit as it is
unpacked, looking for dents, scratches, or other damage. If damage is evident, immediately file a
claim against the carrier and notify the manufacturer.
It is recommended that the shipping container be kept, for possible shipping, should the unit
require repair or maintenance services. If a damage claim has been filed, the container will be
needed, to prove shipping damage.
The laser is a turnkey system, designed so that a field service engineer is not required to get the
system up and operating properly. The system has undergone extensive testing to verify its
conformance to the specifications, prior to delivery.
Before operating the laser, however, it is important to fully understand its main features and
controls.
CAUTION: Do not power up the system before thoroughly reading the
system description. Use of the controls or adjustments, or performance of
procedures other than those specified in this user’s manual my result in
hazardous radiation exposure, laser system damage or result in voiding
the warranty. Please do not connect the main power until you verify the
power switch is in the OFF position.

5. JEWEL LASER APPLICATION

Page 18 Jewel Manual v1.6 | Quantum Composers
Figure 12 Jewel Software Application Main Window
LASER OPERATION CONTROL
The user is responsible for ensuring a suitable beam path and appropriate beam dumps are
provided, before firing the laser.
1. Pulse Mode –Options are continuous, single shot or burst.
a. Continuous mode –The laser will fire continuously from the time the Fire button is
pressed until the Stop button is pressed. The pulses per second are controlled with
the Rep Rate parameter, under System Settings.
b. Single Shot –The laser will output 1 single laser pulse when the Fire button is
pressed.
c. Burst mode - The laser will output the number of laser pulses specified by the Burst
Count parameter, under System Settings. The laser will stop firing at the end of the
burst.
2. Diode Current –Current, in Amps, per pulse sent to the laser diode. See the system ATP
document for the optimal value.
a. System alignment should typically be done at diode current levels 10 to 20 Amps
below the optimum setting.
3. Diode Pulse Width –In µsec it is the width of the diode current pulse. See the system ATP
document for the optimal value.

Jewel Manual v1.6 | Quantum Composers Page 19
4. Diode Trigger- The diode can be internally or externally triggered. Default is internal
trigger.
5. Qswitch Enable –This box must be checked for normal operation. When not selected, the
qswitch will not function preventing output from the laser head.
6. Qswitch Delay –In µsec it is the delay from the start of the diode pulse. See the system
ATP document for the optimal value.
7. Qswitch Trigger –The Qswitch can be internally or externally triggered. Default is internal
trigger.
8. Wait Count –This setting is in pulses and represents the number of diode pulses before the
qswitch is triggered. For example, a setting of 3 would pulse the diode 3 times the qswitch
would function on the 4th diode pulse. This parameter is applied to all Pulse Modes.
9. Divide By N –This parameter will set the qswitch to function on every XX diode pulse. For
example, a divide by value of 2 will trigger the qswitch on every 2nd, 4th, 6th… diode pulse.
10.Fire button –Selecting the fire button will start laser output. NOTE: the laser must be
enabled before the Fire button becomes active.

Page 20 Jewel Manual v1.6 | Quantum Composers
The laser has undergone extensive testing to verify its conformance to the specifications prior to
delivery.
Once the laser has been set up as outlined in the previous chapter, it is ready to operate. Turn
the Key Switch ON. After approximately 10 seconds the laser is initialized and ready for operator
control. See summary Data Sheets included with our laser for factory preset operating
parameters.
CAUTION: Below is a list of guidelines, which apply to all Quantum Composers’
laser systems. These guidelines should be followed whenever possible, to avoid
laser damage.
Operate the laser in a dust-free environment, and keep the Laser Optics covered when not
in use. This protects the output aperture against dust and particulate.
The Laser Optics Assembly is sealed with careful attention to use of low outgassing
materials. Silicone and similar sealing, bonding or insulating materials should not be used
in close proximity to the Laser Optics because these substances will outgas, and could
contaminate the output window, causing laser damage.
Avoid back reflections. Back reflections of even a small percentage of the output energy
can promote damage to optical components in the Laser Head. For example, an uncoated
convex lens or a glass disk calorimeter will reflect about 4% of the incident energy. While
the reflection may seem harmless, it can perturb the resonator operation to the extent that
the near field beam intensity profile is degraded, and may promote optical damage. It may
also affect the resonator hold-off, which can cause prelasing and catastrophic optical
damage. In some cases, even anti-reflection coated glass optics can reflect enough
energy to promote damage to laser optics. It is best to use only quality optics coated for
the operating wavelength.
CAUTION: To avoid laser damage, minimize back reflections of the output beam.
When reflections are unavoidable, direct them away from the optical axis of the
system by canting the optics off-axis. Failure to do so can cause laser damage and
void the warranty.
MANUAL SHUTTER OPERATION
The Jewel Laser utilizes a manual shutter, located at the output of the laser head (see Figure 13).
The shutter blocks laser output when in the CLOSED position. An internal switch prevents the
laser from firing. The switch is satisfied only when the lever is fully in the OPEN position.
