Research Progress of 2μm Waveband Laser Crystals

Abstract

Abstract: 2μm waveband laser crystals in common use are some of host crystals (e.g. YAG, YAP and YLF) doped with Ho, Tm and Er ions. In this paper, a comprehensive dispatch of some 2μm waveband laser crystals on their feature and application background was described. The spectrum characteristics, energy structures of some important 2μm waveband laser crystals were discussed in detail. The latest research progresses on a variety of devices were introduced. Suggestions on the development direction of 2μm waveband laser crystals for LD pumping were made.

Key words: 2μm waveband laser crystal, energy structure, spectrum characteristic, laser-diode pumping
