摘要

在808nm光纤耦合输出的LD激励下

Nd:KGW辐射出很强的橙黄光

测量了上转换荧光谱

其峰值出现在67

631

610

40nm处.分析了其产生的可能跃迁过程

讨论了上转换过程对Nd离子红外激光振荡的影响和上转换激光应用的可行性

并与Nd:YLF的上转换光谱进行对比研究.研究表明

对高掺杂Nd:KGW晶体在高功率抽运下会发生光子雪崩过程

Nd离子在两种材料中均出现黄绿波段的上转换荧光

其上转换激光较难实现.

Abstract

Upconversion of rare-earth ions has been paid more attention because of its application in visible laser and display area.Nd:KGW radiated yellow-orange luminescence under excitation of 808 nm diode laser

and the upconversion spectrum was measured.The upconversion emission peak wavelengths are at 657

631

610

596 and 540 nm.We analyzed the mechanism

and discussed the effect of upconversion on the infrared laser of Nd ions.The feasibility of Nd upconversion laser is also discussed.For comparison

the upconversion emission spectrum of Nd:YLF was also measured.The results indicated that the photon avalanche process was happened when high-doped Nd:KGW was excited by high power 808 nm LD

and yellow-green upconversion luminescence happened in the two materials doped with Nd ions.It's difficult to generate upconversion laser of Nd.
