INSTRUCTIONS FOR SAFETY USE
1. Heat dissipation
Reliability of this LD is deeply correlated with junction temperature. Under higher operating temperature, the reliability deteriorates soon. Heat dissipating device (material: Aluminum, Copper) should be
attached to the base of the LD, and cooling devices (air, water, peltier etc.) should be operated with the LD in order to dissipate the heat from the LD, so that the operating temperature is kept within the
absolute maximum ratings.
2. Safety for operators and users
This LD emits invisible laser radiation. It's classified into Class 4 according to the laser product standards of the IEC 60825-1 (Safety of laser products Part 1 : Equipment classification, requirements and user's
guide) and/or ANSI Z136.1 (American National Standard for Safe Use of Lasers) etc. Direct or reflected laser beam from this LD may damage eyes or skin by being absorbed by cell. The operator must not
stare the emitting area of LD, must avoid direct exposure to the laser beam.
