Normally the output power is from 1600mW - 2400mW. There are many brands for these 2w laser diode, such as : Sony,SANYO,Mitsubishi,OSRAM, Nichia,ROHM, and the most popular is Nichia NDB7875-E 9mm 2w blue laser diode. BeamQ sells most of the 2w laser diodes, you can find them here. However if you want to get 2w laser diode from eBay, you will find that many of them are 2w laser modules , not diodes. A laser diode is a laser where the active medium is a semiconductor, similar to that found in a light-emitting diode. The most common laser diode is formed from a p-n junction. It's powered by injected electric current. The former devices are sometimes referred to as injection laser diodes, to distinguish them from optically pumped laser diodes. Double heterostructure lasers,a layer of low bandgap material is sandwiched between two high bandgap layers.
