*1 The Laser can NOT be lasing under CW operating without External Cavity. Pulse 0.5μs,

Duty 20%

*2 There is some range in ambient temperature. *3 Full angle at 50% from peak intensity.

*4 Monitor Current is short time power reference purpose only. Not guaranteed for

accuracy. This value must be affected intensely by feedback from composing optics.

All figures in this specification are measured by Nichia's method and may contain measurement deviations.

Diffractive feedback efficiency to the Laser diode must be limited less than 30 % under the External cavity configuration.

This model can only be performed under CW operating with External Cavity.

This model is Test Sample for evaluation or design purpose only. Life time is not guaranteed.

The above specifications are for reference purpose only and subjected to change without prior notice.

Safety of Laser light



Laser Light can damege the human eyes and skin. Do not expose the eye or skin to any

laser light 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.



These LDs are classified in Class 4 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 Nichia LDs are incorporated and/or integrated.
