Direct Green Laser Diode: new revolution in green laser technology

The new revolution in green laser technology provides excellent stability even at extreme temperatures!
In the past, the bad news for green laser modules is that green lasers are more sensitive to extreme temperatures than red lasers. People once thought that green lasers were meant to perform poorly at low and high temperatures, but not anymore. If you try this non-DPSS green laser module, you will find out that our green lasers have excellent stability even at extreme temperatures. Operating Temperature Range: -20°C to +65°C (-4 °F to 149 °F).

Why choose direct green laser module?

Direct Green Lasers are direct-diode semiconductor lasers. The stability of the laser output is greatly improved.

Most green laser product on the market are using DPSS (diode pumped solid state) laser modules. DPSS (Diode-Pumped Solid State) is a conventional laser module that emits an infrared laser diode with a wavelength of 808nm and turns it into green by crystal. This is actually a very inefficient way of producing a laser beam as there is significant power loss.

For Direct Green Laser diode, the semiconductor laser itself emits directly. The stability of the laser output is greatly improved since there is no additional crystal. Thanks to their good efficiency, the temperature increase of the lasers during operation is minimized. A long lifetime and high reliability at continuous operation is guaranteed.
