Abstract

We report on the crystal growth, spectroscopic properties and visible laser performances of Pr-doped SrLaMgAlO (ASL). ASL crystals doped with 2 at.% and 4 at.% Pr were grown by Czochralski method. The laser experiments were carried out in a plane-concave resonator under excitation at 486 nm, provided from a 2ω-OPSL. Efficient laser emission was obtained with an 8 mm long sample of Pr(2at.%):ASL. The maximum output power amounted to 267 mW, 52 mW, and 318 mW at an absorbed power of 1.2W for red, orange, and deep red emission, respectively.

摘要

我们报道了掺镨的SrLaMgAlO（ASL）的晶体生长、光谱特性和可见激光性能。采用提拉法生长了掺杂2at.%和4at.%镨的ASL晶体。激光实验在平面-凹面谐振腔中进行，由2ω-OPL提供486nm的激发光。用8mm长的Pr(2at.%):ASL样品获得了高效激光发射。对于红色、橙色和深红色发射，在1.2W的吸收功率下，最大输出功率分别达到267mW、52mW和318mW。
