FLINT ultrafast Yb oscillator

FLINT ultrafast Yb oscillator

The FLINT oscillator is based on Yb:KGW crystal end pumped by high brightness laser diode module, generating femtosecond pulses with high output power in the range of few watts (pulse energy up to 25 nJ).

Generation of femtosecond pulses in the FLINT is provided by Kerr lens modelocking. This results in excellent pulse contrast due the high nonlinearity inherent for optical Kerr effect.

The standard repetition rate of FLINT oscillator is 76 MHz but the oscillator can be equipped with an external electrooptical pulse picker and appropriate timing electronics allowing selection of a single pulse at repetition rates up to 100 kHz.

Typical output power of the FLINT is in the range of 1-2 W (available up to 4 W). Spectral bandwidth is within 10-30 nm (FWHM) with an external compressor yielding a corresponding pulse duration of < 60 fs.

The FLINT oscillator output power can be actively stabilized by power lock function. The oscillator can also be equipped with optional, wavelength converter (HIRO) providing harmonics radiation at 515 nm, 343 nm and 258 nm wavelengths.

The FLINT is ideally suited to seeding of Yb/Nd based ultrashort pulse laser amplifiers and for broadband terahertz generation.
