Coherent Inc.Request Info
Coherent Inc. has introduced 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. 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, consistent with all Sapphire LP lasers, 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 for ease of installation and operation.

A physical variable that is proportionally similar to another variable over a specified range. An analog recording contains data that is similar to the source.
flow cytometry
A method of measuring the characteristics of microscopic particles, usually cells, as they flow in a fluid stream through a beam of light. Particles may be stained with fluorescent dye and the fluorescence detected via laser illumination.
