Where to Buy Distributed Feedback Lasers

Distributed feedback lasers (DFB lasers) simultaneously provide smooth, tunable control of wavelength and the extremely narrow spectral width required for precise fiber optic communication and spectroscopy applications. Integrated modules provide further narrowing of the spectral line in a compact OEM package that features simple tuning interface.

G&H offers a broad range of DFB lasers in the C-band and L-band on 50 or 100 GHz channel spacing as well as at 1310 nm, 1064 nm, and custom wavelengths. Power level options include 40–100 mW out of the fiber for high power 14-pin lasers and 10-18 mW options for high bandwidth 7-pin configurations.

Narrow-band distributed feedback diode lasers with free-space beam or fiber coupling at numerous wavelengths: 1030 nm, 1047 nm, 1053 nm and 1064 nm are available from stock. In order to match the gain maximum of popular amplifying media as seed lasers, temperature tuning and wavelength selection are offered for the above standard laser wavelengths.

SHIPS TODAY: Fiber-coupled DFB laser diodes (1030 nm DFB, 1064 nm, 1310 nm, 1550 nm or any wavelength between 1250 nm and 1650 nm) are offered as stock items or associated with a CW or pulsed laser diode driver. They are compatible with our high speed nanosecond pulsed drivers or low noise laser diode driver for ultra-narrow linewidth single frequency emission. The single-mode laser diode can reach high powers up to 500 mW in the nanosecond pulse regime. Most turn-key diode & driver solutions are optimized for single-shot to CW performances with pulse durations down to 1 ns. The laser diode precision pulses are generated internally by an on-board pulse generator, or on demand from an external TTL signal.
