The L850VG1 from Thorlabs is a 2 mW AlGaAs VCSEL Laser Diode that operates at 850 nm. This VCSEL diode features single longitudinal and single lateral mode operation. It outputs a circular Gaussian beam. This laser comes in a TO-46 package with a G pin configuration. It emits invisible light, which can be hazardous to the human eye. Products which incorporate these devices have to follow the safety precautions found in IEC 60825-1 “Safety of laser products”.
