A broadband dye laser pumped by a frequency-doubled Nd:YAG laser with a full width at half-maximum from 592 to 610 nm was created for the use in a dual-pump broadband coherent anti-Stokes Raman spectroscopy (CARS) system called width increased dual-pump enhanced CARS (WIDECARS). The desired broadband dye laser was generated with a mixture of Pyrromethene dyes as an oscillator gain medium and a spectral selective optic in the oscillator cavity. A mixture of Rhodamine dyes was used in the amplifier dye cell. To create this laser, a study was performed to characterize the spectral behavior of broadband dye lasers created with Rhodamine dyes 590, 610, and 640 and Pyrromethene dyes 597 and 650, as well as mixtures of these dyes.
通过倍频Nd:YAG激光泵浦产生了一种宽带染料激光器，其半高全宽为592至610 nm，用于一种名为宽度增加双泵浦增强相干反斯托克斯拉曼光谱（WIDECARS）的双泵浦宽带相干反斯托克斯拉曼光谱（CARS）系统。所需的宽带染料激光器是通过使用吡咯亚甲基染料混合物作为振荡器增益介质以及振荡器腔中的光谱选择光学元件产生的。罗丹明染料混合物用于放大器染料池。为了制造这种激光器，进行了一项研究，以表征由罗丹明染料590、610和640以及吡咯亚甲基染料597和650以及这些染料的混合物产生的宽带染料激光器的光谱行为。
