few-cycle™ Fiber
The unique few-cycle pulse compresion system allows to shorten the pulse duration of your laser. Spectral broadening of the input pulses in the hollow-core capillary fiber allows for subsequent pulse compression or other desired nonlinear effects, such as white-light generation for 2D spectroscopy and other applications.
