Highly Efficient Nanosecond 1.7 μm Fiber Gas Raman Laser by H<sub>2</sub>-Filled Hollow-Core Photonic Crystal Fibers
We report here a high-power, highly efficient, wavelength-tunable nanosecond pulsed 1.7 μm fiber laser based on hydrogen-filled hollow-core photonic crystal fibers (HC-PCFs) by rotational stimulated Raman scattering. When a 9-meter-long HC-PCF filled with 30 bar hydrogen is pumped by a homemade tuna...
