Typical Performance Curves
Notes
1. Laser beam is harmful especially for your eyes. Don't look at the laser beam directly.
2. Lifetime of the diode laser varied with the operating temperature inversely. We advise that
the TEC cooler should be used to keep the temperature suitable.
3. For turning on the diode laser, please increase the current gradually to the specified
operating value. For shutting down the diode laser, please decrease the current to zero
gradually, and then turn off the power.
4. Please wear static proof bracelet when operating.
5. Please connect the pins of the diode laser correctly as the picture shown in the manual.
6. The operating current must less than the rated current. Otherwise the diode laser should
be damaged.
7. The fiber facet should be keep clean before the diode laser is operating.
8. Please use the constant-current source to avoid the surge.
9. Diode laser should be short circuit when stop using.
10. Bend diameter of the fiber must be larger than 4cm temporarily and 8cm permanently.

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.

Bending diameter of the fiber cannot be allowed to be less than 4cm. When bending the fiber,
please make sure the starting point is away larger than 4cm from the fiber root. When moving
the laser, please don`t directly use fiber (yellow part). Not obeying these rules may cause
fracture of the laser fiber from the root.

Fiber protection case
Make sure that the module and the fiber are in the same plane.
Cooling system
High-power semiconductor Laser Diodes are temperature-sensitive devices. High temperature will
affect its performance. Its lifetime may also be shortened by working at high temperature. So the
generated heat must be removed in time when the LD is working. Water cooling system or TEC
system is recommended for keeping the LD working at appropriate temperature.
Laser safety instructions
High power laser diodes are high energy laser devices. It is harmful to human body and health.
Any personnel working with or around open lasers must be aware of the following:
Exposure to the laser beam may cause physical burns and can cause severe eye damage.
Proper eye protection should be used at all times. All eye protection should be appropriate for
the radiation wavelength generated by the laser in use.
Exposure to the laser beam may cause ignition of volatile or combustible materials.
Never look directly into the laser output port.
Interlock all rooms in which open beams may be present and post appropriate warnings on or
near the doors. Access to these rooms should be limited to properly trained technicians when
lasers are in use.
Use appropriate protective coverings over all beam paths whenever possible.
Lasers and optical elements should be positioned to keep the beam and reflections below eye
level.
