摘要	A compact broadly tunable visible spectrum laser source which can provide a continuous wave (CW) output or a pulsed output with a picosecond pulse length for use in fluorescence microscopy. The laser source has a quantum-dot external-cavity diode laser optically coupled with a periodically poled nonlinear crystal waveguide in which, two or more tunable wavelengths may be generated substantially simultaneously in the visible spectral range. By using an one or more additional diffraction grating and a beam splitter in the external cavity setup to provide the coverage of a broad visible spectral range. Multi-wavelength emission is enabled using a coupled resonator with a beam splitter (6) and at least two diffraction gratings (3,5) and a Quantum-Dot active media (9) to realize the external cavity laser diode. The broad tunable emission is frequency- converted into the visible with a periodically poled waveguide SHG PPKTP (19).
其他摘要	一种紧凑的宽可调谐可见光谱激光源，可提供连续波（CW）输出或脉冲输出，脉冲长度为皮秒，用于荧光显微镜。激光源具有量子点外腔二极管激光器，其与周期性极化的非线性晶体波导光学耦合，其中可以在可见光谱范围内基本上同时产生两个或更多个可调波长。通过在外腔设置中使用一个或多个附加衍射光栅和分束器来提供宽可见光谱范围的覆盖。使用具有分束器（6）和至少两个衍射光栅（3,5）和量子点有源介质（9）的耦合谐振器来实现多波长发射，以实现外腔激光二极管。利用周期性极化波导SHG PPKTP（19）将宽可调发射频率转换为可见光。
