The OEM single frequency DPSS (Diode-Pumped Solid-State Laser) BWG-532-OEM has a nominal wavelength of 532 nm and standard model power output of 20, 50, 100mW before coupling (typically at ≤ 0.5db or a 10.9% insertion loss). This laser with fiber pigtail coupling and terminated with an FC/PC connector, has a unique built-in output power control using a control DC input voltage for a linear purpose. The BWG-532-OEM laser exhibits a single frequency in spectral mode throughout almost the entire rated output power range without any need for external optical attenuators.
