Precision DBR Laser Diodes from Photodigm

17 May 2017

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 760nm through to 1083nm 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 400mW. Couple this power capability with

the high modulation capability (up to 6.8GHz), short pulse durations (<100ps) and

narrow Gaussian linewidths (<500kHz), Photodigm DBR lasers are used as important

frequency standards, calibration references and spectroscopic sources.
