LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 5 mW
WAVELENGTH: 760 - 800 nm
Additional Laser Caution
1. Laser Interlock Mechanism
The position of the switch for detecting loading state is
detected by the system microprocessor, and the design
prevents laser diode oscillation when the switch is pressed
physically.
Thus, the interlock will no longer function if the switch is released
physically and deliberatery.
Laser diode oscillation will continue, if pin 46 of TA2065F (IC2)
on the CD SERVO PCB ASSY is connected to GND, or else
the terminals of Q1 are shorted to each other (fault condition).
