【Abstract】 A high efficient conversion from the Ti:Sapphire laser to the Raman laser with 1053 nm wavelength at the area of picosecond(ps)pulse duration is reported.A Ti:Sapphire laser(808 nm wavelength,450 ps pulse duration and 10 mJ pump energy)is employed as the pump source,acetone is stimulated to generate first-order Stokes wave with 1053 nm central wavelength.Inserting Nd:glass as a fluorescence enhancement medium,the firstorder Stokes wave is obviously enhanced,the energy conversion efficiency from pump laser to the first-order Stokes wave reaches to 17.5%,the bandwidth of the first-order Stokes is 25 nm,and the pulse duration is 318 ps.The physical mechanism together with the potential applications are discussed.更多还原
