3 Laser safety operating instructions
3.1 Laser usage requirements in environment
A ultra-clean environment should be provided for operating the LD. The operating
temperature should be controlled at –10 °C … 45 °C.
Laser safety warning signs should be posted in the working place.
3.2 The requirements on the power supply driving the LD
Constant-current should be available for power supply. The power supply should have
the ability to avoid current or voltage surge at any condition (during start-up,
intermittence or open circuit). The surge would result in instant increase of optical
power, which can cause COMD (catastrophic optical mirror damage).
High power Laser Diodes could operate in forward voltage. The reverse current and
voltage should not be higher than 25 µA and 3 V, respectively.
3.3 Laser operating requirements
Please check the laser safeguard before used the LD. More information about the laser
safe is mentioned in “laser safe” section of this manual.
The semiconductor Laser Diode is a sensitive electronic device. Do not ship or store
near strong electrostatic, electromagnetic, magnetic or radioactive fields. Please
observe precaution for handling electrostatic sensitive devices, such as wearing anti-
static wrist straps, use anti-static packaging material and tools when operation.
Shut off the power supplier before connecting the LD with the power supplier. To shut
off the LD please decrease the current to zero gradually then shut off the power supply.
