Coherent Inc. has announced a family of commercial, all-solid-state optically pumped semiconductor lasers (OPSLs) with output at 552 nm. The Sapphire 552 LP lasers offer continuous-wave output of 50, 75, 100, 150 and 200 mW, rendering them useful for applications in life sciences including flow cytometry, confocal microscopy and drug discovery. They produce a high-quality, diffraction-limited TEM00 beam with M2 <1.1, pointing stability of <5 μrad/°C, high-power stability of <2% and low noise of <0.25% rms from 20 Hz to 2 MHz. The laser head measures 125 x 70 x 34 mm, independent of wavelength and power class. This simplifies integration, including wavelength addition and substitution for OEMs and end users. The devices are equipped with USB, RS-232 and analog interface ports.
