Cooling system

High-power semiconductor Laser Diodes are temperature-sensitive devices. High

temperature will affect its performance. Its lifetime may also be shortened by working at

high temperature. So the generated heat must be removed in time when the LD is working.

Water cooling system or TEC system is recommended for keeping the LD working at

appropriate temperature.

4 Laser safety instructions

High power laser diodes are high energy laser devices. It is harmful to human body and

health. Any personnel working with or around open lasers must be aware of the following:

• Exposure to the laser beam may cause physical burns and can cause severe eye

damage. Proper eye protection should be used at all times. All eye protection should

be appropriate for the radiation wavelength generated by the laser in use.

• Exposure to the laser beam may cause ignition of volatile or combustible materials.

• Never look directly into the laser output port.

• Interlock all rooms in which open beams may be present and post appropriate

warnings on or near the doors. Access to these rooms should be limited to properly

trained technicians when lasers are in use.

• Use appropriate protective coverings over all beam paths whenever possible.

• Lasers and optical elements should be positioned to keep the beam and reflections

below eye level.
