SINGLE-FREQUENCY DFB FIBER LASERS
CW Single-frequency 1 µm Fiber Lasers
CW Single-frequency 780 nm (775 nm, 778 nm) Fiber Lasers
CW Single-frequency 515 nm (532 nm, 546 nm) Fiber Laser
Single-frequency Distributed Feedback (DFB) fiber laser is a fiber laser the seeder of which has a fiber cavity comprising a periodic structure that stands as a distributed reflector within the specific spectrum of wavelengths.
The cavity represents a distributed Bragg reflector. It is made up of two fiber Bragg gratings generating a single-longitudinal-mode (SLM) emission. Usually, there is a phase shift evenly distributed from both sides, in the middle.
Optromix manufactures its own DFB seed fiber lasers in the Erbium (1.5 um) and Ytterbium (1 um) wavelength ranges, and also, using fiber amplifiers and the second, third, and fourth harmonics generators, offers ready-made lasers with wavelengths within the ranges of 1540 – 1575 nm, 1028 – 1112 nm, 770-785 nm, 514 – 556 nm, 354 – 355 nm and 257 – 266 nm. The laser design allows you to tune the wavelength in the range of up to 1 nm using the temperature setting of the seeder. Built-in piezo actuator provides fast piezo tuning with modulation up to 10 kHz.
Optromix single-frequency DFB fiber laser sources are single-mode (TEM00), Mode-hop-free, low RIN noise, and excellent wavelength stability. They are reliable, have high performance, and are easy to use. OEM module versions can be easily integrated with various optical devices.
