The DPSS green laser module is a compact, self-contained laser module designed for use in industrial alignment, medical and scientific applications where a highly visible beam is required.
It produces a very visible circular output beam of <2.0mm diameter and output powers of 0.9mW and 4mW with a maximum operating current of 250mA.
Power stability is better than 5% over 7 hours. Modulation capability of 0-1kHz is standard.
In addition, the module uses a front facet monitor photodiode to maintain a stable output power, as opposed to using the internal monitor of the laser diode, which is often less responsive.
The green laser module consists of an anodized aluminum housing, laser diode, drive circuit and collimating lens. Electrical connections are made via external flying leads.
