O.E.M. Diode Pumped Solid-State Green Lasers
GM- series green laser modules use laser diode
(808nm) pumped Yttrium Orthovanadate (Nd:YVO4) crystal coupled with Pottasium
Titanyl Phosphate (KTP) as a frequency doubler generating 532 nm (green)
and 1064nm (infrared). This method is gaining an increasing popularity
for low power applications because of its high absorption and emission
efficiencies. Lasermate provides a variety of design
with the output power from
1mW to >100mW for 532nm and from
1mW to 300 mW
for 1064 nm. Please see below for more information.
The linear polarization of standard green lasers is
about 4:1. Linear polarizer with
³100:1 is available for all
models of green lasers including modules & systems.
ACC (automatic current control) Circuit design with the
stability of 20% at 25+/- 3 oC for green laser module is good enough
for some applications. We also have developed APC (automatic power
control) Circuit for green laser module to achieve the high stability of output power <±5%
(or <±3% if requested) for more applications. In addition, we also supply High
Performance Low Noise or Single Longitude Mode Green Laser Modules
with TEC
to achieve the high stability of output power <±3%.
