Q-switched microlaser with Nd:La3Ga5,5Nb0.5O14 active medium

Abstract

LD pumped solid state lasers are very attractive for producing of compact systems with different special lasing regimes. In this connection disordered crystals with Ca-gallogermanate structure are one of the most appropriate laser materials with broad (about 4 nm) lasing spectum [1]. Previously it was shown that Nd:La3Ga5.5Nb0.5O14 crystal like other crystals of Ca-gallogermanate group has unique combination of their physical properties [2]. In this research characteristics of LD pumped Q-switched short crystal Nd:La3Ga5.5Nb0.5O14 laser are presented.
