What is an Ultrafast Laser?

Ultrafast lasers are typically defined as any pulsed laser producing pulse widths less than 10 ps (picosecond lasers), down into the femtosecond region (femtosecond lasers) and beyond, which are commonly referred to as ultrashort pulses (ultrashort pulse lasers).

‘Ultrafast Lasers’ is a term that can refer to a number of various types of lasers. However, for our purposes, we are referring to mode-locked fiber lasers. Our ultrafast lasers are produced by mode locking many phase-locked longitudinal modes from a broadband laser or a material with a large gain bandwidth. Because of this, mode locking induces a beat frequency which results in picosecond or femtosecond duration laser pulses. Furthermore, these ultrafast laser pulses are unique for their extremely high peak power and, combined with the ultrashort pulses, are ideal for a number of applications. For example: non-thermal ablationmicromachining, and non-linear spectroscopy including CARS and two-photon microscopy.

Nps Series


The NPS series of ultrafast lasers is the ultimate solution for OEM integrators and researchers working with nonlinear optics applications like OPO pumping and narrowband Raman spectroscopy. The NPS series boasts remarkable features such as up to 10W average output power, <7ps pulse width, and a 40MHz repetition rate. The transform-limited operation, with a spectral width of <0.3nm, and accurate central wavelengths make these lasers a suitable candidate for highly efficient amplification by Nd-doped DPSS amplifiers.
