光学参量啁啾脉冲放大的转换效率受到泵浦脉冲的时空特性的限制。我们展示了一种新颖的混合啁啾脉冲放大方案，该方案使用单个泵浦脉冲并结合光学参量放大和激光放大，以实现高增益、高转换效率和高预脉冲对比度，而无需使用电光调制器。我们的混合放大系统在中心波长为 820nm 时的整体转换效率达到了 37%。通过使用这种简单的方法和商用调Q泵浦激光器可以产生多太瓦脉冲。
Conversion efficiency in optical parametric chirped-pulse amplification is limited by spatiotemporal characteristics of the pump pulse. We have demonstrated a novel hybrid chirped-pulse amplification scheme that uses a single pump pulse and combines optical parametric amplification and laser amplification to achieve high gain, high conversion efficiency, and high prepulse contrast without utilization of electro-optic modulators. We achieved an overall conversion efficiency of 37% from the hybrid amplification system at a center wavelength of 820nm. Generation of multiterawatt pulses is possible by use of this simple method and commercial Q -switched pump lasers.
