7. Operation note
7.1 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℃. 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.
7.2 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.
7.3 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 :
7.3.1 Ground the device and circuits. Install surge filters, surge reduction transformers, or other
electrostatic discharge protectors in the power supply inputs.
7.3.2 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 MΩresistance.
03.08.2010
eld83npt5.doc
8 of 10
7.3.3 Use anti-static containers for transport and storage.
7.3.4 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.
7.3.5 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.
7.4 Soldering
Use a grounded soldering iron to solder laser leads. Solder at a temperature of no more than 250℃
for a maximum of 3 seconds, at a point at least 2 mm from the base of the leads .
7.5 Handling laser diodes
Never touch the glass window of the laser. A damaged or dirtied window will impair the performance of
the laser.
7.6 Handling packages
Due to the glass window in each device, packages must not be dropped or subjected to excessive
pressure.
7.7 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.
8. Quality assurance
8.1
Laser diodes (semiconductor lasers) have a much longer life than other lasers such as gas or
solid-state lasers. The components of our lasers have optimum characteristic ranges. To ensure these
characteristics and product life, we manufacture our laser diodes based on comprehensive data
control using our own custom manufacturing, measuring, and inspection equipment.
8.2
Quality assurance system
8.2.1 After the wafers have been manufactured, electrical and optical characteristics are measured
to verify that characteristics can be achieved as the manufacturing process progresses.
8.2.2 In-process inspections are conducted at various manufacturing points to ensure the stability of
our assembly operations.
8.2.3 All products are burned-in to minimize initial and random failures.
8.2.4 Characteristics of all products are tested before shipping.
8.2.5 Products are managed by wafer lot.
8.2.6 Reliability tests are performed on randomly selected samples.
8.3
Quality assurance measures
8.3.1
Materials, manufacturing conditions, and inspection are controlled and maintained based on
company set standards. Temperature, dust, humidity and other environmental conditions are also
controlled based on company standards.
8.3.2 Measurement instruments used during the manufacturing process are regularly inspected and
calibrated based on company measurement control standards.
9. Security
The laser beam emitted from a laser diode is almost invisible to both the human eye and the
animal eye, however, it will injure the eye and sufficient caution must be exercised to avoid direct
exposure or exposure through a fiber to the beam when a laser diode is in operation.
To adjust the optical axis or perform other similar work, we recommend using an infrared-sensitive ITV
camera.
We also recommend that protective glasses be worn
