Ultrafast 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 a large number of phase-locked longitudinal modes from a broadband laser or from 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 ablation, micromachining, and non-linear spectroscopy including CARS and two-photon microscopy.
Our Products
We offer ultrafast mode locked lasers with pulse widths as short as 100 femtoseconds (100fs) up to 10 picoseconds (10ps). Furthermore, they produce a peak pulse energy up to 60 microjoules (60µJ) and pulse repetition rates up to 80 MHz. These lasers are typically available in the near infrared wavelength region. However, frequency doubling allows the generation of visible outputs in the green spectral region.
