Laser safety operating instructions
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.
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.
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.
 The operating current of laser must not be higher than the given rate current. The excessive
current would accelerate aging and shorten lifetime, even damage the LD.
 Keep the fiber pigtail clean. In non-working environment, you must use the protection case to
avoid fiber pigtail from being polluted. If you need to clean the fiber pigtail, use ethanol or
water-free alcohol cotton balls and wipe fiber pigtail gently.

 LD must be taken out of the fiber protection case before it starts to work.
 When laser is working, please don’t point it straight to the fiber as shown below the yellow part,
in order to prevent the fiber protection case from being damaged by high-power laser
generated heat.
