Passively Q-Switched Operation of a Tm,Ho:LuVO4 Laser with a Graphene Saturable Absorber

Abstract

A passively Q-switched (PQS) operation of Tm,Ho:LuVO 4 laser is experimentally demonstrated with a graphene saturable absorber (SA) mirror. An average output power of 1034 mW at 54.5 kHz is acquired with an 8% optical-optical conversion efficiency. The energy per pulse of 40.4 µJ and a peak power of 56.07 W are achieved; the narrowest pulse width of 300 ns is acquired, and the output wavelengths of Tm,Ho:LuVO 4 are 2075.02 nm in a continuous wave (CW) regime and 2057.03 nm in a PQS regime.

“…Few-layer materials are of great importance to researches and applications due to their unique optical and electronic characteristics. Current researches on few-layer materials are principally focused on graphene, insulating hexagonal boron nitride (hBN), topological insulators (TIs), black phosphorus (BP), and transition metal dichalcogenides (TMDs) [1][2][3][4][5][6]. Among these materials, TMDs are a large family, which exhibits a variety of photo-electric properties and offers a wide range of applications in broad research fields [5,6].…”

Yu reports a pulsed Tm,Ho:LuVO 4 solid-state laser with a repetition rate of 54.5 kHz and an output power of 1034 mW. The emission wavelength shifted from 2075.02 nm to 2057.03 nm when the operation mode was switched from continuous wave to Q-switched [11]. The last paper in this section, authored by D. Yu, Y.…”

“…Graphene can be used extensively ultrafast photonics, optical switching, and photoelectric detectors. [16][17][18] Considering the excellent properties of graphene, other twodimensional (2D) nanomaterials, for instance transitional metal sulfides, topological insulators (TI), and black phosphorus (BP), have also come into the limelight. Recently, other low-dimensional nanomaterials are introduced as saturable absorber to generate pulse laser, as bismuthene quantum dots, sulfur-doped graphitic carbon nitride, TiO 2 /CuO nanocomposites, single crystalline BiOCl nanosheets.…”

“…Graphene has attracted more attention due to its remarkable electrical and thermal conductivities, easy fabrication, zero band gap, and cost‐effectiveness. Graphene can be used extensively ultrafast photonics, optical switching, and photoelectric detectors 16–18 . Considering the excellent properties of graphene, other two‐dimensional (2D) nanomaterials, for instance transitional metal sulfides, topological insulators (TI), and black phosphorus (BP), have also come into the limelight.…”
