Abstract

Extremely simple and efficient 1.24 micrometers phosphosilicate fiber-based Raman laser was developed. The cavity of the Raman laser was formed by the Bragg gratings written directly in the phosphosilicate fiber. The investigation of the laser parameters, mathematical simulations and optimization of the Raman laser were carried out. As a result of optimization the 1.24 micrometers output power of 2.4 W was reached at the neodymium fiber laser pump power of 3.6 W, that corresponds to the Raman laser quantum efficiency of 77%.
