TOPTICA’s DLC DFB pro lasers integrate both distributed-feedback (DFB) and distributed Bragg reflector (DBR) lasers. Available wavelengths include 633 nm and the entire range from 760 nm to 3500 nm. Three laser heads accommodate different diode packages. Due to the absence of alignment-sensitive components, the DLC DFB pro lasers exhibit an exceptional stability and reliability.

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.
