Abstract
Unique spectroscopic properties of trivalent ytterbium ions in aluminium perovskite crystals (YAlO3, LuAlO3) make these crystals good candidates for picosecond and femtosecond lasers active media. The features of soliton and non-soliton mode-locking of Yb:LuAP laser were studied. Maximum average output power of 7W with pulse duration of 130fs and 28.1 % optical efficiency were obtained in soliton mode-locking regime. Average output power up to 12W with 2ps pulse duration and 38% optical efficiency obtained in nonsoliton mode-locking regime. Chirped pulse regenerative amplifier based on Yb:LuAP crystal was investigated. Pulse duration as short as 165fs with output power of 4.5W at 200kHz pulse repetition frequency were demonstrated.
