Coherent Launches Sapphire SF - Ultra Narrow Linewidth OPSLs at 488 nm and 532 nm
Coherent Sapphire lasers are based on the company's unique, optically pumped semiconductor laser (OPSL) technology. This is a well-proven technology with over 25,000 units currently in the field. Moreover, OPSL technology features extremely low output noise because its short upper state lifetime completely eliminates the "green noise" that limits the noise performance of many other solid state-lasers. They also don't suffer from thermal lensing issues commonly found in frequency doubled DPSS lasers (e.g. Nd:YAG). Plus, OPSL technology is both wavelength and power scalable.
These new Sapphire SF lasers are ideal for research and OEM applications that require a narrow spectral linewidth and/or a long coherence length. Primary applications include Raman spectroscopy, Brillouin scattering, holography/stereography, interferometry, metrology, inspection, and remote optical sensing.
