钛宝石晶体的高掺钛浓度和高激光破坏阈值对提高其单程增益系数至关重要。目前国际上及国内常用的引上法及热交换法生长技术很难解决高掺钛问题,从而得不到高掺钛浓度及高峰值吸收系数的晶体。而上海光机所研制的钛宝石激光晶体在高掺钛浓度和高激光破坏阈值方面最有特色,由邓佩珍研究员领导的课题组用独创的生长高温难熔氧化物晶体新技术,研制出了高掺钛蓝宝石激光晶体,经不断研究
The high Ti doping concentration and the high laser damage threshold of Ti: sapphire crystals are crucial for increasing the one-way gain coefficient. At present, both the international and domestic commonly used lead-in method and heat-exchange growth technique are difficult to solve the problem of high titanium content, so that the crystals with high titanium concentration and high peak absorption coefficient can not be obtained. The titanium laser crystal developed by Shanghai Optical Machinery is the most distinctive in the fields of high titania concentration and high laser damage threshold. The research team led by Prof. Deng Peizhen developed a new high-temperature refractory oxide crystal technology with high Titanium-doped sapphire laser crystal, after continuous research
