紧凑型多像素参量光源
A compact, multi-pixel parametric light source
摘要：
讨论了一种结构紧凑、单通道、多像素光学参量发生器的特点。用一组聚焦的强激光束抽运三硼酸锂晶体，产生了数百个独立的高空间质量可调谐超短脉冲。通过用大泵浦光束照射微透镜阵列来产生光束阵列。已报道的信号和闲频的总转换效率高达30%的泵浦光束。对于所产生的辐射，拍摄到拍摄的能量波动下降到3%。
英文摘要：
The features of a compact, single pass, multi-pixel optical parametric generator are discussed. Several hundreds of independent high spatial-quality tunable ultrashort pulses were produced by pumping a bulk lithium triborate crystal with an array of tightly focussed intense beams. The array of beams was produced by shining a microlenses array with a large pump beam. Overall conversion efficiency to signal and idler up to 30% of the pump beam has been reported. Shot-to-shot energy fluctuation down to 3% was achieved for the generated radiation.
