Pulsed Fiber Lasers

Fiber LasersOur pulsed fiber lasers are q-switched or mode locked, providing pulse widths from 125ns down to 100fs, with pulse energy ranging from 25nJ up to over 1mJ, average output powers ranging from 150mW to 100W, and are available in wavelengths ranging from 1565nm (short-wave infrared or SWIR) down to 532nm (green) through the use of second harmonic generation. OEM laser packages and modules are available.

Pulsed Fiber Laser sources are a specific subset of DPSS lasers where instead of a crystal being used as the gain medium a doped fiber optic cable is used. Typically they are doped with rare-earth elements, such as erbium, ytterbium, or neodymium just like the crystals used in most DPSS laser systems.

Fiber lasers have several advantages over traditional DPSS lasers, all of which are derived from the geometry of the fiber optic itself, namely the innate ability to have an extremely long single-mode optical cavity.  This geometry allows for the production of either extremely high-power single-mode lasers producing unprecedented brightness, or extremely narrow band lasers with near perfectly single frequency output.

Our pulsed fiber lasers are used in a wide range of applications including multi-photon microscopy, optogenetics, fluorescence lifetime, 3D scanning, LiDAR, micromachining, surface treatment, thin film removal, welding, and many more!
