1.4. Emission warning indicator
An emission warning indicator is fitted to the laser head cover adjacent to the output aperture. When
the indicator is illuminated, the laser is capable of emitting harmful laser radiation.
DANGER
Risk of injury to eyes and exposed skin
This is a Class 4 (Class IV) laser product. All precautions relevant to this class of laser product
should be strictly observed. Use of controls or adjustments or performance of procedures other
than those specified herein may result in hazardous radiation exposure. Strict compliance with
the safety precautions set out and referred to in this manual and extreme care in use are
essential to minimise the chance of accidental damage to the equipment or personal injury.
Luxinar does not accept liability for any damage or injury howsoever caused or arising.

1.5. Maximum Permissible Exposure and Nominal Ocular Hazard Distance
The Maximum Permissible Exposure (MPE) is the level of radiation to which, under normal
circumstances, persons may be exposed without adverse effects. The MPEs represent the maximum
level to which the eye or skin can be exposed without consequential injury and are related to the
wavelength of the laser radiation, the pulse duration or exposure duration, and the tissue at risk.
The MPEs given in the following tables are informative and provided so that the integrator can calculate
the Nominal Ocular Hazard Distance (NOHD), perform a risk analysis and inform the user about the safe
usage of the product. However, exposure limits for the eye and the skin of employees in the work place
and the general public are in many countries specified in national laws. These legally-binding national
exposure limits might differ from the MPEs given in the tables below.
The NOHD is the distance from the output aperture beyond which the beam irradiance or radiant
exposure remains below the appropriate MPE. Importantly, the NOHD is dependent upon the beam
waist size and the divergence of the beam. Therefore, the NOHD is dependent upon the optical
components acting on the beam. The NOHDs given in the tables below are relevant only when the laser
is operated without external beam delivery attached. When beam delivery is attached it is the
responsibility of the integrator or end-user to recalculate the NOHDs. Further details of the safe use of
lasers are given with IEC/ TR 60824-14 "Safety of laser products – Part 14: A user’s guide."

Figure 15 - Diffusion cooled slab laser components
Figure 15 shows the principle of operation of a slab laser. A gas discharge (8) forms the active laser
medium and is established between the wave guide electrodes (9) by a radio frequency voltage (5, 10).
The rear mirror (7) and output mirror (3) form the optical resonator. The laser beam (1) is produced
within the resonator and is emitted through an output window (2). Liquid coolant flowing between the
input (6) and output (4) is used to cool the electrodes.
2.2. Laser head — standard version
The OEM 65iX laser is a high-frequency RF excited, diffusion-cooled CO2 slab laser designed for industrial
use as a cutting, welding or marking tool.
Due to the configuration of the electrodes in a slab laser, the emitted laser beam diverges at different
rates in the x (free space) and the y (waveguide) directions. In order to make the beam circular the
output beam is reshaped using reflective correction optics. This may be achieved by using single optical
elements or the combination of cylindrical and spherical elements.
Depending on the configuration of the resonator, there may also be diffraction effects due to the output
optic of the resonator. This can produce secondary lobes on the main output beam that need to be
scraped or filtered out. This is achieved by the use of a spatial filter.
After beam reshaping and spatial filtering, the beam quality is ideal for any material processing
operation that requires excellent mode quality and stability.

2.3. Laser head — shutter version
The OEM 65iX can be fitted with a safety shutter to block the laser output. The shutter is designed as a
safety device and is not intended to operate as a continuous beam block or process shutter.
When closed, a mirror within the shutter assembly deflects the beam into a beam dump. The beam
dump absorbs all the energy of the laser beam and will become very hot if the laser is run for a long
period with the shutter in the closed position.
Safety circuitry in the OEM 65iX controller provides interlocking so that laser output is disabled
whenever the shutter is in the closed position. In addition, opto-sensors continuously monitor the open
and closed status of the shutter.
The shutter module contains a laser diode pointer that outputs a low-power visible red laser beam
coaxial with the main laser beam. This visible beam provides an indication of where the main laser beam
will hit the material to be processed.
2.4. DC power supply (optional)
Contact Luxinar for more details of power supply options.
