Abstract

A large number of Yb3+-doped laser crystals are investigated as active media for ultrafast oscillators and amplifiers in last decades. Yb:CALGO (Yb:CALYO) crystals demonstrate promising spectroscopic properties that confirmed by excellent experimental results in mode-locked lasers provided near-transform limited pulses with wide spectra (up to 51nm [1]). Despite this the large number of investigated femtosecond Yb-based regenerative amplifier (RA) systems were seeded by fs-pulses with narrower spectrum (≤15nm [2]) that can limit the amplified pulse bandwidth. In our paper we present for the first time to the best of our knowledge the results of experimental investigation of Yb:CALYO-based chirped pulse RA seeded by broad-band (60 nm FWHM) pulses.
