A passively mode-locked of Tm:YAP laser with a zeolitic imidazolate frameworks-8 (ZIF-8) saturable absorber

Abstract

Metal-organic framework materials have shown outstanding potential and applications in many fundamental fields, while the zeolitic imidazolate frameworks-8 (ZIF-8) material has received little attention. In this paper, ZIF-8 particles have been used as a saturable absorber (SA), which favors the Tm:YAP solid-state laser (SSL) working well in a passively mode-locked（PML）mode. Under the PML mode, an average output power of 912 mW is obtained from the laser with a pulse width of 737 ps at 97.98 MHz. Also, the as-calculated per pulse energy and the peak power are 9.3 nJ and 12.6 W, respectively.
