High Performance, Narrow Linewidth Laser Diodes

UK58-0830

LASER COMPONENTS is delighted to announce a partnership with Photodigm - the world’s leading specialist manufacturer of single spatial and longitudinal mode laser diodes.

Spanning the wavelength range from 760 nm through to 1083 nm and including critical wavelengths in spectroscopy for K, Rb, Cs, He and O₂, these highly reliable DBR devices really do set the standard of performance within a range of applications including Raman ­spectroscopy, atom cooling and trapping, biomedical diagnostics, difference frequency and frequency doubling, LiDAR, oxygen and water vapour sensing. Custom wavelengths are available on request. Devices are available in a range of packages including C-mount, butterfly, TO-8 and as chips on submount.

Photodigm’s PreciseMode™ delivers a nearly circular, weakly divergent beam with a >2nm mode-hop-free tuning range. Also, as an OEM solution for high power application, the ­Mercury™ TOSA package is available, specialised for cooled laser operation.

Emitting diffraction limited beams, devices from Photodigm can provide outputs approaching maximum theoretical brightness with higher wavelength options demonstrating output powers of up to 400 mW. Couple this power capability with the high modulation capability (up to 6.8 GHz), short pulse durations (<100 ps) and narrow Gaussian linewidths (<500 kHz), Photodigm DBR lasers are used as important frequency standards, calibration references and spectroscopic sources.
