Abstract: A narrow-linewidth, single-spatial-mode single-pass fiber-amplifier based light source is described that provides high-efficiency and high reliability. The major components of the design include: a narrow-linewidth single-spatial-mode semiconductor seed laser, a seed-laser PM optical isolator, a multimode semiconductor pump laser, a fiber-based PM combiner, an active gain fiber, and a frequency doubling crystal. The design is particularly suited for use as a high-power light source for numerous scientific and engineering applications, including: a Raman spectroscopic imaging microscope system and atomic clocks/atomic trapping and cooling.
