【摘要】掺钕铍酸镧－Ｎｄ￣（３＋）：Ｌａ＿２Ｂｅ＿２Ｏ＿５（Ｈｄ￣（３＋）：ＢＥＬ）激光晶体为单斜晶系，其荧光谱具有线性偏振特性。本文用提拉法生长了Ｎｄ￣（３＋）：ＢＥＬ单晶，并对晶体结构进行了分析，对其光谱特性（吸收、偏振荧光谱，低温谱及荧光寿命等）和激光二极管（ＬＤ）泵浦的激光特性进行了研究，并和Ｎｄ：ＹＡＧ晶体进行了比较。更多还原

【Abstract】 In this paper, the Nd￣（3+）La₂Be₂O₅ Crystal was grown by CZ method. The crystal construction ofNd￣（3+）:La₂Be₂O₅ is analysed.The absorption spectra,polarization flu-orescence spectra（77K, 300K ）and fluorescent lifetime（τ=135±5μs） of Nd￣（3+）:La₂Be₂O₅ crystal were measured.The crystal is suitable with LD pump based on the analysis of spectroscopic properties and compare with Nd￣（3+）: YAG crystal.更多还原
