摘要
以CdSe晶体光参量振荡器为代表的中红外激光器在生物、医疗和**等诸多领域有着广泛的应用前景。本文总结了生长CdSe单晶的工艺方法包括熔体法、熔剂法和气相法等, 其中常用的为气相法, 近年来高压垂直梯度冷凝(HPVGF)技术也逐渐被采用。国内外将本征CdSe晶体用于光参量振荡器件(OPO), 适用于多种激光器泵浦源, 且输出功率不断提高。而Cr2+的掺杂能有效提高泵浦效率, 实现波长的连续可调。
Abstract
The mid infrared laser, represented by the CdSe crystal optical parametric Oscillator, has a wide range of applications in many fields such as biology, medical treatment and military. In this paper, the methods of growing CdSe single crystal include melt method, flux method and gas phase method, in which gas phase method is most common, and the HPVGF technology has been gradually adopted. The intrinsic CdSe crystal used as OPO device is applied to kinds of laser, and the output power is increasing. Doping of Cr2+ can effectively improve the pumping efficiency and realize continuous wavelength adjustment.
