Paper Abstract

The neod:yni.iu.-rn-doped la.11.thanu..'n. beryllate (Nd:3+La2Be20 5 or Nd3+EL) laser crystal is biaxial crystal with monocli...'1ic structure. Linearly polarized laser oscillation at 1. 07 and 1. 079 μm are observed. Spectroscopic measurements and a.."'18.lysis ofLD pumped operation ofNd3.,.:BEL crystal at 1.07 μ."'11 (300K0 ) have been performed.The Nd ions doped concentration in BEL host is higher than in YAG over 40% and vithout apparent concentration quench. So, it ca.11 increase the laser efficiency greatly and ca.TJ. decrease laser rod size. For the stronger and broader absorption bandwidth of Nd3+:BEL crystal, it is suitable to LD pumping .. Key words: laser crystal; biaxial crystal; crystal structure; polarization spectra; LD pump; crystal pulling
