Abstract

Lasers from 1 I 6 to 3 F 4 transitions were first demonstrated in a Pr 3+ :YLF crystal by inserting a birefringent filter.Output powers up to 2.44 W, 2.10 W, 2.01 W, and 2.42 W were obtained at 691.7 nm, 701.4 nm, 705.0 nm, and 708.7 nm, respectively.Their slope efficiencies were 19.8%, 16.5%, 15.8%, and 19.4%, respectively.The M x 2 and M y 2 factors were measured to be 2.29 and 2.03 at 691.7 nm, 2.23 and 1.86 at 701.4 nm, 2.31 and 2.08 at

691.7 nm, 701.4 nm， 705.0 nm和708.7 nm的高功率Pr3+:YLF连续波激光器

通过插入双折射滤光片，在pr3 +:YLF晶体中首次展示了从1 I 6到3 f4跃迁的激光。在691.7 nm、701.4 nm、705.0 nm和708.7 nm处，输出功率分别达到2.44 W、2.10 W、2.01 W和2.42 W。其坡度效率分别为19.8%、16.5%、15.8%和19.4%。在691.7 nm处测得m2和m2因子分别为2.29和2.03，在701.4 nm处测得m2和m2因子分别为2.23和1.86，在691.7 nm处测得m2和m2因子分别为2.31和2.08

期刊介绍： Chinese Optics Letters (COL) is an international journal aimed at the rapid dissemination of latest, important discoveries and inventions in all branches of optical science and technology. It is considered to be one of the most important journals in optics in China. It is collected by The Optical Society (OSA) Publishing Digital Library and also indexed by Science Citation Index (SCI), Engineering Index (EI), etc. COL is distinguished by its short review period (~30 days) and publication period (~100 days). With its debut in January 2003, COL is published monthly by Chinese Laser Press, and distributed by OSA outside of Chinese Mainland.
