Safety of Laser light

• Laser Light can damage the human eyes and skin. Do not expose the

eye or skin directly to any laser light and/or through optical lens. When

handling the LDs, wear appropriate safety glasses to prevent laser

light, even any reflections from entering to the eye. Focused laser

beam through optical instruments will increase the chance of eye

hazard.

• This LD is emitting invisible light.

Cautions

1. Operating methode

• This LD shall change its forward voltage requirement and optical ouput power according to

temperature change. Also, the LD will require more operation current to maintain same ouput

power as it degrades. In order to maintain output power, use of APC (Automatic Power

Control) is recommended. Which use monitor feedback to adjust the operation current.

• Confirm that electrical spike current generated by switching on and off does not exceed the

maximum operating current level specified herein above as absolute maximum rating. Also,

employ appropriat countermeasures to reduce chattering and/or overshooting in the circuit.

2. Static Electricity

• Static electricity or electrical surges will reduce and degrade the reliability of the LDs. It is

recommended to use a wrist trap or anti-electrostatic glove when handeling the product.

3. Absolute Maximum Rating

• Active layer of LDs shall have high current density and generate high electric field during its

operation. In order to prevent excessive damage, the LD must be operated striclty below

absolute maximum rating.
