Typical Performance Curves
Notes
1. The 635nm high power laser diode radiated high power red beam .Don't look at the laser
light directly, because it's harmful to eyes.
2. High-power semiconductor laser diodes are temperature-sensitive devices. The high
temperature will effect the performance of the products. The lifetime can also be
shortened by high temperature. So the generated heat must be removed in time when
the LD working. The water cooling system or TEC system are recommended for keeping
the LD at a suitable temperature.
3. Increase the current gradually to the specified operating value. For shutting down the
laser diode, please decrease the current to zero gradually, and then turn off the power.
Pleaser sure that the power supply have no current overshoot at any time. High power
laser diodes could operate in forward voltage. The reverse current and voltage should
not be higher than 25 mA and 3 V, respectively.
4. Be careful to keep the facet cleaning and prevent mechanical transmission.
Contamination of facet will result in rapid degradation of devices. The chip of LD is
fragile. Please do not use any hard thing to touch the chip.
5. The high power laser diode arrays are very sensitive to electrostatic. Please wear anti-
static bracelet during operating with the laser diodes.
6. The operating temperature should be controlled at –10°C … ~70°C. A clean, dry and
ventilated environment should be available when storing and operation. Dew can
damage the laser diodes. Please check the model number of the laser diodes before you
take it, and ensure the appearance test.
