非线性晶体中的光学参量啁啾脉冲放大(OPCPA)有可能产生极大的峰值功率和平均功率，但其能量受到晶体生长问题的限制，或平均功率受到晶体热光特性的限制。近年来，大尺寸(直径7.5厘米×长25厘米)的氧硼酸钇钙(YCOB)晶体被生长出来，并被用于高平均功率的二次谐波产生。此外，YCOB还具有将OPCPA系统扩展到接近1微米波长的高峰值和平均功率运行所需的必要热光特性。我们报告了据信是YCOB首次用于禁毒办的情况。解决了对更高峰值和平均功率的可扩展性问题。
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-average-power second-harmonic generation. Further, YCOB has the necessary thermo-optic properties required for scaling OPCPA systems to high peak and average power operation for wavelengths near 1 microm. We report what is believed to be the first use of YCOB for OPCPA. Scalability to higher peak and average power is addressed.
