Abstract
Multi-µJ narrow-bandwidth (≈ 10 cm(-1)) picosecond pulses, broadly tunable in the visible-UV range (320-520 nm), are generated by spectral compression of femtosecond pulses emitted by an amplified Ti:sapphire system. Such pulses provide the ideal Raman pump for broadband femtosecond stimulated Raman spectroscopy, as here demonstrated on a heme protein.
摘要
通过对放大钛宝石系统发出的飞秒脉冲进行光谱压缩，产生了多微焦窄带宽（约10厘米⁻¹）皮秒脉冲，其在可见光 - 紫外范围（320 - 520纳米）内具有广泛的可调谐性。这种脉冲为宽带飞秒受激拉曼光谱提供了理想的拉曼泵浦，正如在一种血红素蛋白上所展示的那样。
