Operation notes
1. Absolute maximum ratings
If an excessively large current flows in a laser diode, a large optical output will occur and the emitting facet may sustain
damage. This optical damage can occur even with momentary over-current. For this reason, absolute maximum ratings
which must not be exceeded even momentarily have been established. Exercise particular caution with respect to the drive
voltage supply and static electricity. We guarantee use within the absolute maximum ratings. These ratings are established
for a case temperature of 25_C. As the temperature of a laser diode increases, its maximum output will decrease and the
operating range will shrink. Even when operated within the absolute maximum ratings, operation at high temperature will
result in a shorter life than operation at low temperature. For this reason, the design should include sufficient margin for heat
radiation and light output.
2. Heat radiation conditions
Like other semiconductors, prolonged operation of a laser diode will cause heat to build up at junctions and increased case
temperature. For this reason, attach aluminum, copper (or other) heat sinks (at least 30 _ 30 _ 3mm) to the stem of the laser.
3.Protection against damage due to electrostatic discharge and other current surges
Electrostatic discharge and other current surges can cause deterioration and damage in laser diodes, resulting in reduced
reliability ,We advise taking the following protective measures :
1)Ground the device and circuits. Install surge filters, surge reduction transformers, or other electrostatic discharge
protectors in the power supply inputs.
(2) When working with laser diodes wear anti-static clothing, including footwear and caps. Materials should be selected
carefully.’ Grounded wrist should always be worn while working with laser diodes, and the strap should be grounded through
a 1 Mresistance.
(3) Use anti-static containers for transport and storage.
(4) Laser deterioration and damage can occur due to excessive current spikes when the power is turned on or off. Design
circuits to avoid the generation of excessive current spikes.
(5) Inductive surges near equipment that emits high frequency EMI can damage or destroy lasers. Avoid using lasers near
fluorescent lamps or other sources of EMI emissions.
4. Soldering
Use a grounded soldering iron to solder laser leads. Solder at a temperature of no more than 250_C for a maximum of 3
seconds, at a point at least 2 mm from the base of the leads.
5.Handling laser diodes
Never touch the glass window of the laser. A damaged or dirtied window will impair the performance of the laser.
6. Handling packages
Due to the glass window in each device, packages must not be dropped or subjected to excessive pressure.
7. Safety
It is extremely dangerous to look, either directly or through a lens, at the laser beam emitted from a laser diode. Use a TV
camera or other similar device to adjust the optical axis.
