Specifications
detailed information
Designed to replace expensive DFB, DBR, fiber, and external cavity lasers, the spectrum stabilized laser offers superior wavelength stability over time, temperature (0.007 nm/°C), and vibration, and is manufactured to meet the most demanding wavelength requirements. The 14-pin butterfly package is available at wavelengths ranging from 633 nm – 2400 nm as a stand-alone component, in an integrated OEM module, or in a fully integrated module with user configurable temperature and power control electronics. Lasing wavelength can be accurately specified and repeatedly manufactured to within 0.1 nm upon request. The butterfly package is configured for a collimated open beam. The laser is ideal for high resolution Raman spectroscopy, confocal microscopy, direct-diode frequency doubling, laser seeding, gas sensing, metrology and remote sensing applications.
