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 M Ωresistance.
