Laser Diodes

 I offer them from just the bare diodes to full copper laser modules with drivers and choice of glass lens. I use only the best silicone wire. This wire has been tested to handle 5A. It is super flexible and burn resistant.

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.
