2W 462nm M462 Blue Diode

The wait is finally over. No more deep blues with a hint of violet. M462 a true blue diode. Listing is for a single 5.6mm 2W M462 462nm blue diode. Max suggested running current is 1.8A. @ 1.8A with a single element lens like a G-2 these average over 2.1W. A laser diode is a current-driven device which is should not to be driven by a voltage source. Otherwise electrical over stress 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.
