Abstract

In this paper, TaSe2 material was prepared and used as a saturable absorber (SA) to modulate a Tm:YAP laser. Under the continuous-wave mode, an 18.31 W diode laser was used to pump the Tm:YAP crystal, and an output power of 6.22 W was achieved at 1993.1 nm with an optical–optical conversion efficiency of 33.9%. Under the passively Q-switched mode, the Tm:YAP pulse laser was modulated by a TaSe2-based SA, and a 2.8 W average power and a 440 ns pulse width at 73.15 kHz were obtained at 1988.4 nm, corresponding to an optical–optical conversion efficiency of 15.2% and a per pulse energy of 38.2 µJ.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
