Abstract

Recent progress in the development of GaInN laser diodes in the blue region enables solid-state lasers in the visible spectral range without frequency conversion. This was demonstrated to be a highly efficient process in for example praseodymium doped materials [1]. But also the trivalent holmium ion provides absorption lines in the blue spectral region and emission lines around 550 nm. However, so far laser action on this transition has only been realized at low temperatures [2,3]. Since the energy gap between the thermally coupled 5S2 and 5F4 manifolds - the initial states of the green emission - and the adjacent 5F5 level is only about 2700 cm−1, low phonon hosts as for example Lu2O3 (Eeff,phon = 550 cm−1) are required to minimize non-radiative losses. We report a fundamental spectroscopic research of Ho:Lu2O3 in order to evaluate the laser potential of the green transition. Crystals were grown by the Heat-Exchanger and Nacken-Kyropoulos method and the spectroscopic investigations include temperature dependent lifetime measurements as well as the determination of the ground state absorption, the excited state absorption, and the emission cross sections.
Ho:Lu2O3的光谱学与可见激光的实现
蓝色区域GaInN激光二极管的最新进展使固态激光器在可见光谱范围内无需频率转换。这被证明是一个高效的过程,例如镨掺杂材料[1]。但是三价钬离子也提供了蓝色光谱区域的吸收线和550纳米左右的发射线。然而,到目前为止,激光对这种转变的作用仅在低温下实现[2,3]。由于热耦合5S2和5F4流形(绿色发射的初始状态)与相邻5F5能级之间的能隙仅约2700 cm−1,因此需要低声子主体(例如Lu2O3 (Eeff,phon = 550 cm−1))来最小化非辐射损失。我们报道了Ho:Lu2O3的基本光谱研究,以评估绿色跃迁的激光势。晶体通过热交换器和Nacken-Kyropoulos方法生长,光谱研究包括温度依赖寿命测量以及基态吸收,激发态吸收和发射截面的测定。
