In this paper, we experimentally investigated the extreme frequency shift in high-power Raman fiber laser (RFL). The RFL was developed by using a pair of fiber Bragg gratings with fixed and matched central wavelength (1120 nm) combined with a piece of 31-m-long polarization maintaining (PM) passive fiber adopted as Raman gain medium. The pump source was a homemade high-power, linearly polarized (LP) wavelength-tunable master oscillator power amplifier (MOPA) source with ${\sim}25~\text{nm}$ tunable working range (1055–1080 nm). High-power and high-efficiency RFL with extreme frequency shift between the pump and Stokes light was explored. It is found that frequency shift located within 10.6 THz and 15.2 THz can ensure efficient Raman lasing, where the conversion efficiency is more than 95% of the maximal value, 71.3%. In addition, a maximum output power of 147.1 W was obtained with an optical efficiency of 71.3%, which is the highest power ever reported in LP RFLs to the best of our knowledge.

In this paper effect of a fiber laser on the microstructure and properties of steels 95X18 and 12X18H10T is shown. The regularities of changes in the structure of a laser-treated surface by X-ray diffraction and X-ray microscopic analyzes were studied. The high efficiency of laser heat treatment of steel 95X18 with the subsequent tempering, to improve the tribological properties of the surface layers has been established. For steel 12X18H10T laser shock hardening method (405 HV) is recognized to be effective.
