Energy and average power scalable optical parametric chirped-pulse amplification in yttrium calcium oxyborate.

Optical parametric chirped-pulse amplification (OPCPA) in nonlinear crystals has the potential to produce extremes of peak and average power but is limited either in energy by crystal growth issues or in average power by crystal thermo-optic characteristics. Recently, large (7.5 cm diameter x 25 cm length) crystals of yttrium calcium oxyborate (YCOB) have been grown and utilized for high-averag...

Thermal properties of borate crystals for high power optical parametric chirped-pulse amplification.

The potential of borate crystals, BBO, LBO and BiBO, for high average power scaling of optical parametric chirped-pulse amplifiers is investigated. Up-to-date measurements of the absorption coefficients at 515 nm and the thermal conductivities are presented. The measured absorption coefficients are a factor of 10-100 lower than reported by the literature for BBO and LBO. For BBO, a large variat...

Pump-seed synchronization for MHz repetition rate, high-power optical parametric chirped pulse amplification.

We report on an active synchronization between two independent mode-locked lasers using a combined electronic-optical feedback. With this scheme, seed pulses at MHz repetition rate were amplified in a non-collinear optical parametric chirped pulse amplifier (OPCPA). The amplifier was seeded with stretched 1.5 nJ pulses from a femtosecond Ti:Sapphire oscillator, while pumped with the 1 ps, 2.9 µ...

Regenerative spectral and pulse shaping of high average power chirped pulse thin-rod Yb:YAG amplifier

Spectral gain narrowing of high-average power, regenerative chirped pulse thin-rod Yb:YAG amplifier was compensated by the regenerative spectral and pulse shaping technique. An average output power of 18 W was achieved at a repetition rate of 100 kHz with an output pulse width of below 1.2 ps. A wide spectral bandwidth of 2.5 nm was also observed. 2009 Optical Society of America OCIS codes: (1...

High Power Femtosecond Fiber Chirped Pulse Amplification System for High Speed Micromachining

The need for improved precision in a wide variety of micromachining applications has driven scientific interest in ultrashort pulse lasers. Despite numerous demonstrations of reduced heat effect and improved processing quality, the utility of such lasers has been limited by the heavy demands placed upon laser performance. In addition to high contrast laser pulses with minimal pulse-to-pulse flu...
