532nm CW Laser, 300mW DPSS Laser

The Excelsior 532nm CW Laser is offered by Spectra-Physics. Using patented frequency doubling techniques the compact 532nm CW laser achieves impressive conversion efficiency for lower power consumption and long term reliability. The single longitudinal mode 532nm DPSS laser is available in output powers from 50mW to 300mW with a M2 of <1.1. The spectral linewidth has been measured to be <10 MHz with a wavelength frequency drift of less than 50 MHz/°C.

The continuous-wave (CW) laser is a compact design with outer dimensions of the laser head of 95 mm x 28 mm x 36.5 mm. This compact design makes it ideal for OEM system integration. The controller is available in either an OEM version or benchtop version. The benchtop version is ideal for laboratory use and the compact laser head makes it easy to integrate into a dense optical table.

Careful attention to the design ensures long term reliability and stability of the 532nm laser. The elliptical beam has a Pointing Stability <6 μrad/°C with power stability measured over 8 hours of <±1% fluctuations. Laser noise is <0.2% rms measured over 20 Hz–20 MHz bandwidth.
