本文报道了二极管泵浦Pr掺杂的白钨矿结构LiYF(4)、LiLuF(4)和LiGdF(4)氟化物晶体的生长、光谱和激光结果。我们测量了(3)P(0)能级的偏振相关吸收和发射特性以及衰变时间。利用(3)P(2)在444 nm附近的吸收，在GaN激光二极管泵浦下，获得了从绿光到近红外的多次跃迁，获得了高效的激光发射。(C)2008年美国光学学会
In the present work we report on the growth, spectroscopy and laser results of diode pumped Pr-doped LiYF(4), LiLuF(4) and LiGdF(4) fluoride, scheelite-type structure crystals. We measured the polarisation dependent absorption and emission properties as well as the decay time of the (3)P(0) level. Exploiting the (3)P(2) absorption around 444 nm, we obtained efficient laser emission under GaN laser diode pumping on several transitions from the green to the near infrared wavelength range.
