| 摘 要： | 采用拉曼带通滤光技术,以调QYAG倍频激光器为激发光源(532nm),在普通单色仪上记录到液相苯的拉曼谱。拉曼带通滤光器(RNF∶Raman Notch Filters)可使杂散光降低10~8量级。应用拉曼带通滤光器直接对YAG倍频输出激光线型进行观察,观察到了与基频相对应的弱跃迁伴线结构。

| Abstract: | Newly developed Raman Notch Filters (RNF) were applied to the following cases:a. Using RNF as a pre-filter of a common monochromator to record Raman spectra of benzene, the exciting wavelength was the second harmonic generation of a Q-switched YAG pulsed laser (532 nm). b:Observing the stimulated emission due to the weak transition near 1.064 μm in a Q-switched frequency-doubled Nd3+:YAG laser with RNF as laser (532 nm) suppression apparatus. RNF can suppress the straylight at the laser wavelength by a factor of 108. |
