General Hazards
Danger –Serious Personal Injury
This Class 4 laser product emits invisible infrared laser radiation at 10.6µm.
Do not allow laser radiation to enter the eye by viewing direct or reflected laser
energy. CO2laser radiation can be reflected from metallic objects even though
the surface is darkened. Direct or diffuse laser radiation can inflict severe corneal
injuries leading to permanent eye damage or blindness. All personnel must wear
eye protection suitable for 10.6µm CO2radiation when in the same area as an
exposed laser beam. Eyewear protects against scattered energy but is not
intended to protect against direct viewing of the beam.
Never look directly into the laser output aperture or view scattered laser
reflections from metallic surfaces.
Enclose the beam path whenever possible. Exposure to direct or diffuse CO2
laser radiation can seriously burn human or animal tissue, which may cause
permanent damage.
This product is not intended for use in explosive, or potentially explosive,
atmospheres.

Introduction
This guide provides the basic information needed to operate an Iradion Laser. This laser is
designed for use while integrated within a system and is not designed to meet CDRH
requirements as a stand-alone product. As such, the user must be aware of certain
requirements before use.
CDRH
This is an OEM laser component that has been designed for integration into a functioning laser
system. As a stand-alone device, it cannot be turned on and therefore does not incorporate all
of the safety features required by the Center for Devices and Radiological Health (CDRH).
Provisions for the incorporation of these safety features are available, and it is expected that the
user will apply them and fully comply with all CDRH requirements.
Available Safety Features
The following safety features are available as electronic signals on the laser’s HD-9 control connector:
Interlock
Upon contact closure, allows the system to operate. An
open connection will disallow the laser from firing.
Key switch
Upon contact closure, allows the laser to fire after
imposing a 5-second delay. (Key switch function is
program version dependent.)
Power up in Fault
Requires the key switch to be cycled. (Program version
dependent.)
Lase signal
Output signal indicating the laser is firing.
Fault signal
Output signal indicating the malfunction of an internal
component or the electronics.
Indicator lights
DC Power, Temp Warning, Interlock, Fault, Ready, Lase

10 | P a g e
System Overview
Iradion CO2lasers are available in the following rated wattages: 23, 30 & 40 Watts. Each model
has a maximum power output that exceeds their rated wattages, and all models feature identical
footprints, so they all integrate RFPA and cooling in one package. Two connectors in the rear
provide the interface to control signals, power, and returns diagnostic signals and faults signals.
Connector pins and associated electronics are protected against static ESD damage. DC power
is applied to the one-meter power cord.
Caution
There are no user-serviceable parts under the cover. The RF cover must be removed
according to procedure; otherwise, damage could occur. The RF cover edges are RF sealed
to the top heat sink, which makes it very difficult to slide off the cover. The laser may not
operate properly without the cover in place. There are dangerous RF voltages under the
cover that will cause serious RF burns to the skin if touched.
Caution
The lasers are waveguide lasers with a “slab” unstable optical resonator. The resulting elliptical
beam is corrected by a cylindrical lens in the black extension tube mounted to the faceplate.
This assembly is exactly positioned so that the beam direction is close to the original elliptical
beam. Removal of the cylindrical lens assembly will result in the loss of this original alignment
and will require a procedure for replacement.
Caution
The optical intensity at the cylindrical lens is VERY high (>6000W/cm2).
Any contamination to the optical surface could cause runaway destruction of the lens. Do
NOT burn materials close to the lens or leave fingerprints on the lens.

Caution
This unit is provided with a 1-meter length of cable for DC power. If the wire is extended
in length, #10 wire must be used. Do not add more than 1-meter additional wire unless
it is heavier than #10. Power supply regulation should be greater than ±2% and ripple
no greater than 400 mV. No damage can occur to the laser if the DC voltage is in the
range of 0 to 50 Volts; however, the laser will only operate at the specified voltage.
Check your power supply before attachment and adjust it to the specified voltage. The
software will not allow more than -2/+1.5 Volts variation including line drops at high
current settings. If output becomes intermittent and the fault light flashes on and
off, the voltage drop on the power cable may be too large or the power supply
may be bad. If the fault light lights up on power up, check the power supply
voltage setting.

“F” Type Lasers
Current production lasers with fan-cooling are marked E25, E30 & E40. These lasers are
designed to control fan operation internally based on the operating temperature. The fan will
start operating at 32°C or higher and will stop at 30°C or lower. This fan function is enabled via
commands sent over the RS 232 lines. If the fans do not start when power is applied, this means
that the fan function is disabled. If fans do not start with power up, this does not indicate fan
malfunction! Factory fresh lasers are always shipped with the fan function disabled. See the
Iradion LCC Comm Protocol_v1.5 for information on communicating with the laser control card.

14 | P a g e
Operation of Unit
1. Mount the laser in a manner such that the beam will strike a target capable of absorbing
up to 80 Watts of power. Make sure that the airflow openings are clear of any
obstructions.
2. Confirm that the signal connections to the laser are secure and tight. Make sure that
the power supply is correctly adjusted and is capable of delivering a minimum of the
rated amps plus 2 amps margin.
3. Connect the laser power leads to DC, Red + using at least 10-gauge wire. The power
supply can affect laser performance! Use a high-quality, well-regulated supply.
4. Power up the DC supply. The fans should start. (The “F” fan option, when programed,
will not start the fans until the laser reaches a preset temperature.)
5. Make sure the "INTERLOCK" switch is down or off, or the interlock line is ungrounded.
6. The Key Switch line must be toggled from off to on to arm the laser. If the switch is
closed when power is applied, turn it off and then on. There will be a 6 second delay
before the green "READY" light lights up. (This switch must be toggled to arm the
system after power up.) NOTE: This function depends on the software version
and programing. OEM lasers are shipped without this function.
7. When the system arms to "READY", if the tickle is being applied, the "LASE" light
should also light up when the interlock is enabled. The "LASE" light will get brighter as
the power increases; this is normal.
8. The “Mod Hi” connection to the laser requires that the command signal contain a tickle
pulse of 1 to 3 S at 5,000 Hz when the laser is not being commanded to fire. Tickle
rates of greater than 5,000 Hz will result in dangerous conditions (possible unexpected
low-level emissions). When the laser is being commanded, the modulation rate can
reach up to 200 KHz. NOTE: OEM lasers may be shipped with the tickle function
disabled. In this case, the user must provide the correct tickle protocol at all
times.
9. Make sure there is enough cool air available to dump the heat! Do not obstruct the air
flow in any way or modify the fans. The laser should not be near heaters or other heat
sources that increase the ambient fan inlet temperature.

15 | P a g e
Tickle Pulse
This option is supplied by the customer, Iradion DOES NOT supply the tickle pulse inside the
laser.
Laser Command Signals
During laser bench testing, it is recommended that command signals be generated from an
Iradion Laser Controller or properly programed pulse generator. These units can provide the
tickle pulse and drive signals needed to test and operate the laser properly. Alternatively, most
motion control software packages are designed to provide the proper pulse protocol.
The Modulation pins on both the “D” connector, pins 1 (high) and 6 (low) and the RJ-45, pins
1 (high) and 6 (low) are designed to allow either floating or grounded input modes.
Both the High and Low pins should be used in either case. A software setting made
through the RS232 interface will either ground Modulation Low or leave it floating. Factory
setting is set to ground Modulation Low.
It is possible to use the Modulation High pin only if the Modulation Low pin is grounded by
software settings or by a physical wire; however, depending on the ground integrity of the host
system and level of ground noise this may not be the best solution.
The diagram below shows the circuit of the modulation input interface:

16 | P a g e
System Test
The operation of the laser is possible after the above connections are completed. To test the
laser, apply power and the tickle command signal. If the software settings require a key switch,
toggle it off and on. After about 6 seconds, the system will be armed.
The interlock connections must be closed to operate the system.
Fault conditions can be detected by viewing the LED indicators on the rear of the laser. The
signals monitored with LEDs are:
LASER READY
Lights up when the laser controller is ready for operation.
OVERTEMP
Lights up when the RFPA is getting too hot. Faults at Temp limit.
FAULT
Lights up when the controller is in a Fault state.
LASE LED
Lights up whenever signals are delivered to the RFPA FET bias.
POWER
Lights up whenever DC power is applied.
INTERLOCK
Lights up when the interlock switch is closed.
