We report efficient amplification of chirped supercontinuum pulses in a two-stage stimulated Raman amplifier based on double tungstate [()] crystals, pumped with 1.2 ps transform-limited pulses at a 1030 nm wavelength. The second stage demonstrates a conversion efficiency of 55% with an output pulse energy of 0.6 mJ at a 1135 nm wavelength. The amplified Stokes bandwidth is 10 times the pump bandwidth, providing 145 fs pulses after compression.
我们报道了基于双钨酸盐[()]晶体的两级受激拉曼放大器中啁啾超连续谱脉冲的高效放大,该放大器由波长为1030 nm的1.2 ps变换极限脉冲泵浦。第二级在波长为1135 nm时展现出55%的转换效率,输出脉冲能量为0.6 mJ。放大后的斯托克斯带宽是泵浦带宽的10倍,压缩后可提供145 fs的脉冲。
