A red-emitting tapered diode laser with a monolithically integrated distributed Bragg reflector grating is presented. The device is able to emit up to 1 W of spectrally stabilized optical output power at 5°C. Depending on the period of the tenth order surface grating the emission wavelengths of these devices from the same gain material are 635 nm, 637 nm, and 639 nm. The emission is as narrow as 9 pm (FWHM) at 637.6 nm. The lateral beam quality is M(2)(1/e(2)) = 1.2. Therefore, these devices simplify techniques such as wavelength multiplexing and fiber coupling dedicating them as light sources for µ-Raman spectroscopy, absolute distance interferometry, and holographic imaging.
本文介绍了一种具有单片集成分布布拉格反射器光栅的红色发光锥形二极管激光器。该器件能够在5°C下发射高达1W的光谱稳定光输出功率。根据第十阶表面光栅的周期，由相同增益材料制成的这些器件的发射波长分别为635nm、637nm和639nm。在637.6nm处，发射线宽窄至9pm（半高宽）。横向光束质量M(2)(1/e(2)) = 1.2。因此，这些器件简化了诸如波长复用和光纤耦合等技术，使其成为用于μ拉曼光谱、绝对距离干涉测量和全息成像的光源。
