The 658-nm FCLM series fiber-coupled laser modules provide typical and maximum linewidths of 30 and 50 MHz, respectively, and coherence length >10 m with a precise center wavelength. Available from Ondax Inc., the lasers are stabilized using the company’s volume holographic grating PowerLocker. It is controlled via a manual switch or through a D-Sub 9 connector and can be operated in CW or modulation mode. Wavelength is locked to <±1 nm. Custom wavelengths are available. Measuring 110 × 56 × 26.5 mm, the lasers have applications in metrology, sensing, flow cytometry, Raman spectroscopy and analytical instrumentation.
