Laser Diodes

Offered as bare diodes, options for them in easy to incorporate into end products 12mm, 20mm and 25mm diameter copper laser modules with various back half, lens and some with basic driver circuits. They are wired with high quality extremely flexible silicon wire. The 26 gauge has 64 strands and is tested to handle 5A.

A laser diode is a current-driven device which is should not to be driven by a voltage source. Otherwise electrical

overstress may occur to the laser diodes as the operation voltage varies from device to device and additionally depends on the case temperature. Special care has to be taken, when switching the electrical power on and off, as transient currents beyond the maximum ratings can occur damaging the laser diode. To operate laser diodes correctly , a proper electrical driving mechanism has to be employed. A proper laser diode driver must act as an accurate constant current source with good transient protection and very low noise.

Furthermore, please note that at different temperatures the output power of the laser

diode will change. Thus, for applications that require a constant output power over a broad range of temperatures active temperature control is necessary.
