Yb:LuAlO crystal as a gain medium for efficient broadband chirped pulse regenerative amplification.

The experimental study results of a chirped pulse amplification regime are reported for the Yb:LuAlO 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.
