 Bending diameter of the fiber cannot be allowed to be less than 4cm. When bending the fiber,

please make sure the starting point is away larger than 4cm from the fiber root. When moving

the laser, please don`t directly use fiber (yellow part). Not obeying these rules may cause

fracture of the laser fiber from the root.

 Make sure that the module and the fiber are in the same plane.

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.

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.
