L15 Series Operator Manual 9
Safety Information
FDA and Federal Regulations
Access Laser Company has designed our lasers to comply with CDRH requirements set
forth by United States’ Radiation Control Health Act of 1968. Therefore the L15 series
lasers meet all standards for laser products under 21CFR 10.40.10 and 21CFR
1040.11. These standards have been set forth to protect the end user from harmful
radiation. It is the responsibility of the end user to assure compliance with any and all
regulations related to final use or when used outside the United States.
Never Open the Laser
To prevent direct exposure from the laser beam and injury to the user, do not try to
open the laser. Opening the laser may result in burns or eye damage or misalignment of
the laser or other damage to the laser. The end user will never need to open the laser
for maintenance or any other reason. All laser parts are serviceable only by authorized
Access Laser personnel. Disassembling the laser voids any warranty. Use of controls,
adjustments or performance procedures other than those specified herein may result in
hazardous exposure.
Eye Protection Required
The L15 series lasers are Class IV lasers. Class IV Lasers have power outputs of
greater than 500 mW. This laser can cause mild to severe burns if skin or eyes are
exposed to the beam or scattered radiation. Protective eyewear should be worn at all
times.
Use Appropriate Beam Blocks
The L15 series lasers produce laser radiation around 10.6µm. This wavelength is
invisible and requires special equipment to detect or view. Some materials may cause
the laser beam to reflect and scatter, causing injury or damage. Take precautions to
block the beam from unintentional reflection. Avoid using materials such as copper,
aluminum, or gold as beam blocks which are highly reflective and may cause the beam
to scatter. Organic materials may be flammable when exposed to the laser beam.
Never use organic materials such as plastic or wood as a beam block. Use a beam
block designed for the wavelength and power of your laser, or use a laser power meter.
CAUTION Super-Pulse Lasers
For Super Pulse lasers (-P model), running the laser above a 25% duty cycle or 400µs
pulse length may damage the RF driver. The internal protection program will interrupt
the user signal beyond these parameters, making the output inconsistent.

Laser Operation Instructions
Operating the Laser
1. Close the laser shutter (if present).
2. Direct the laser toward an appropriate target, such as a power meter or a beam-
blocking device. (See Safety Information regarding appropriate beam blocking
devices.)
3. Secure the laser to a bench top using the mounting holes in the laser body.
Do not torque, twist or bend the laser body during the mounting process. Applying
uneven pressure to the laser body may distort the laser body, causing poor
performance and possible damage.
4. Connect the Cooling System
a. Air Cooled Lasers (where cooling is provided by the end user)
i. If no cooling is built in to your laser, you are responsible for providing
sufficient cooling to maintain the laser specifications. (See Air Cooling
Section for specifications.)
ii. Connect your air cooling system to the laser.
b. Built-in Fan Cooled Lasers
i. Connect the 12V DC supply to the fan power connector.
5. Connect the RF cable to the BNC connector on the laser.
6. Connect the RF cable to the TNC connector on the RF Driver.
7. Connect your 5V TTL source to the TTL gate (BNC connector) on the RF Driver.
8. Set the TTL input to 0V (0V = OFF; 5V = ON).
9. Connect the RF Driver to the appropriate DC power supply.
a. L15: 36V DC
b. L15P: 48V DC
c. L15D: 36V DC for Continuous Wave operation. 48V DC for Super Pulse
operation.
NOTE: Red wire is positive. Black wire is negative.

L15 Series Operator Manual 12
Laser Operation Instructions
Operating the Laser
NOTE: The RF driver can be modulated at frequencies from 0 Hz to100 kHz.
Optimal laser performance can be expected at a frequency range of 1-15 kHz.
10. Install the gate enabling D-sub 15 dongle onto the D-sub 15 connector on the RF
driver.
NOTE: If using the LC3 Controller, plug the LC3 Controller into the D-sub 15
connector, instead of the D-sub 15 dongle.
11. Verify the beam path is pointed at an appropriate beam blocking device.
Eye Protection Required
This laser can cause mild to severe burns if skin or eyes are exposed to
the beam or scattered radiation. Protective eyewear should be worn at all times.
12. Remove the protective tab from the aperture.
13. Open the laser shutter (if present).
Operate the shutter using the lever closest to your body. Never pass
your hand in front of the laser beam to open or close the shutter.
14. Plug in or apply the DC power supply to the RF Driver.
NOTE: The RF Driver is enabled after a 5 second safety delay, as indicated by
the LED on the D-sub 15 dongle. The LED is red during the safety delay and turns
amber when the RF Driver is enabled.
The red LED on the laser indicates the laser is powered. When
the laser is powered it is able to lase upon application of a control
signal.
15. To activate the laser beam, apply 5V through the TTL gate (0V = OFF, 5V = ON).
NOTE: For the Super Pulse operation found in the L15P and L15D, using the 48V
DC power supply, the laser is designed to run up to 25% duty cycle and a pulse
length up to 400µs.
CAUTION
Running above 25% duty cycle or 400µs pulse length may damage the RF driver. The
internal protection program will interrupt user signal beyond these parameters, making
the output inconsistent.

Air Cooling Guidelines
Here are two suggested basic air-cooling configurations of Access Laser products. In
both cases, air flow is directed toward the laser. Air cooling must be symmetric on both
sides of the laser. Otherwise, the laser can develop thermal-mechanical distortions
over the long term.

The table below gives minimum airflow rates required on laser when operating at full
power under normal atmospheric conditions, below 2000 m elevation. It also lists power
to be dissipated for each model. Other cooling options may be possible provided that
the power dissipation specifications and symmetrical cooling are applied.

The laser heat sinks are designed so that standard 60 mm
or 50 mm square fans can be mounted directly to the
laser, as in the photo to the right. In the Lasy-20, for
example, one can mount six 30 CFM fans (3 of them on
each side symmetrically) using self-tapping screws (#6-
7/8” or equivalent.)
