Safety Advice

Laser beam are extremely dangerous to human eyes. Never look

at laser beam directly 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.

The LDs are classified in Class 3B of IEC60825-1 and 21 CFR Part

1040.10 Safety Standards. It is absolutely necessary to take overall

safety measures against User's modules, equipment and systems

into which these LDs are incorporated and/or integrated.

Operating Considerations

Operating the laser diode outside of its maximum ratings may cause failure or a safety hazard.

The diode may be damaged by excessive drive currents or switching transients. If the diode is

operated using a power supply, it is strongly recommended to connect the diode with the output

voltage set to zero. The voltage should then be increased slowly and with great caution, while at

the same time carefully monitoring the laser diodes output power and drive current. The laser

diode will show accelerated degradation with increased temperature, and it is therefor advised to

keep the case temperature low, by means of heat sinking the device.

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

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

appropriate countermeasures to reduce chattering and/or overshooting in the Circuit.
