The present application discloses a cavity dumped low repetition rate infrared tunable femtosecond laser source configured to produce pulses of 200 femtoseconds or less with a peak power of four megawatts or more for use in a variety of applications including multi-photon microscopy.

Low repetition rate infrared tunable femtosecond laser source

A high-power ytterbium-doped calcium fluoride laser system is disclosed herein which includes at least one pump source, at least one laser cavity formed by at least one high reflector and at least one output coupler, and at least one ytterbium-doped calcium fluoride optical crystal positioned within the laser cavity in communication with the pump source, the ytterbium-doped calcium fluoride optical crystal configured to output at least one output signal of at least 20 W, having a pulse width of 200 fs or less, and a repetition rate of at least 40 MHz.

High-power ytterbium doped calcium fluoride mode-locked laser and methods of use

A novel broadly tunable optical parametric oscillator is described for use in numerous applications including multi-photon microscopy. The optical parametric oscillator includes at least one sub-picosecond laser pump source configured to output a pump signal having a wavelength of about 650 nm or less and at least one type II optical parametric oscillator in optical communication with the pump source and configured to generate a single widely tunable pulsed optical signal. In one application, an optical system is in optical communication with the optical parametric oscillator and configured to direct at least a portion of the optical signal to a specimen, and at least one analyzing device is configured to receive a signal from the specimen in response to the optical signal.
