摘      要：In order to develop a laser system for multi-wavelength satellite laser ranging,the joint group of the Shanghai Astronomical Observatory and the Czech Technical University has studied the conversion efficiency of the Raman-shifting beam and its spatial *** adopted a 0.53 μm laser with pulse width of 35 ps and peak energy of 35 mJ,the second harmonic of a Nd:YAG actively and passively mode-locked laser,to pump a one-meter-long Raman tube which is full of H2 with high pressure at the Prague-based *** get the first Stokes laser (0.68 μm):7 mJ (single pulse) with beam divergence of 40 (arcsecond) and spatial wobbling of less than 4;and the first anti-Stokes laser (0.43 μm):2 mJ (single pulse) with divergence of 56 and spatial wobbling of less than 4.The emitting beam from the Raman cell also includes 0.53μm:10 mJ (single pulse) with divergence of 40 and spatial wobbling of less than 7.According to the radar link equation and based on the above on the above obtained multi-wavelength’s energy,we can estimate the detection probabilities for three colors *** is shown by the result that the developed multi-wavelength Raman laser system has the capability of satellite *** Raman laser system will be installed at the laser station in Shanghai Astronomical Observatory to research the multi-wavelength satellite laser ranging.
