Laser Diodes

Offered as bare diodes or mounted in a high quality copper module with silicon leads added and lens options. I use high quality super flexible and burn resistant silicone wire. Diodes with powers below 3W use a 26 gauge wire that has 64 strands tested to handle 5A. Diodes with powers over 3W use a 24 gauge tested to handle up to 8A.

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. 

Note that at different temperatures the output power and wavelength of the laser 

diode will change. For applications that require a stable output power and wavelength over a extended runtime active temperature control is suggested.
