1.5 μm Fiber Gas Raman Laser Source
A 1.5 μm fiber laser generation experiment in gas-filled hollow-core fiber by stimulated Raman scattering is reported. A high pressure ethane-filled hollow-core fiber is pumped with a high peak-power, narrow linewidth, subnanosecond pulsed 1064 nm microchip laser. The 1553 nm pulse with peak power of 16.6 kW is generated via stimulated Raman scattering of ethane. The linewidth is less than 0.2 nm and the pulse duration is about 435 ps. To the best of our knowledge, the peak power obtained here is more than four times of the highest value reported for erbium-doped fibers. The study provides a technical pathway for 1.5 μm fiber laser with both high peak-power and narrow linewidth.
