Abstract
The experimental study results of a chirped pulse amplification regime are reported for the crystal with different polarization states in the gain media for the first time, to the best of our knowledge. Maximum output power of 5 W with 565 fs pulse duration was obtained for E//b-polarization at a 200 kHz repetition rate seeded by a 98 fs Yb:KYW oscillator. 165 fs pulses with output power of 4.5 W were demonstrated for E//c-polarized light in the crystal.
