摘要
金刚石拥有已知材料中最高的热导率、低的热膨胀系数、高度的化学惰性及优异的光学性能,使其能够在机械、光学和材料学等领域满足诸多极端条件的应用需求。近年来随着化学气相沉积制备工艺的提高,使得人造金刚石的光学品质得到快速提升,光学级的金刚石晶体因此也以其优异的拉曼和布里渊特性表现出优异的功率提升、相干性增强以及频率转换能力,并推动金刚石激光器在极大程度上克服了基于传统工作物质的粒子数反转激光器存在的热效应、以及波长和输出功率难以兼顾的难题。文中总结了高功率金刚石激光技术的研究进展,并对金刚石激光器的发展趋势和应用前景进行了展望。
Abstract
With the highest thermal conductivity, low thermal expansion coefficient, high chemical inertness, and excellent optical properties among known materials, diamond can meet the application requirements of many extreme conditions in the fields of mechanics, optics, and materials, etc. In recent years, with the improvement of the chemical vapor deposition preparation technology, the optical quality of synthetic diamond has been rapidly improved, which leads to the optical grade diamond crystals excellent power improvement, coherence enhancement, and frequency conversion ability due to their excellent Raman and Brillouin characteristics. Meanwhile, diamond lasers overcome the thermal effect in the particle number inversion laser based on the traditional gain media, and the difficulty to consider both the wavelength and power. The research progress of high-power diamond laser technology was summarized, and the development trend and application of diamond lasers were prospected.
