Operation of continuous wave and Q-switching on diode-pumped Nd,Y:CaF2 disordered crystal

Highly efficient continuous-wave laser operation of LD-pumped Nd,Gd:CaF2and Nd,Y:CaF2crystals

“…Using the Nd,Y:CaF 2 dis ordered crystal as a gain medium, the mode-locked laser generated pulses with a pulse duration as short as 103 fs, an average output power of 89 mW, and a repetition rate of 100 MHz. Li and Zhang [10][11][12] also conducted many studies and achieved high-quality laser output. In the present paper, the co-doping effect of Gd 3+ and Y 3+ on spectroscopic properties and laser performance was systematically investigated.…”

Passively Q-Switched Nd:YVO 4 Laser Using a Gold Nanotriangle Saturable Absorber

“…[1−3] The passive Q-switching technique is a commonly used method to achieve such lasers due to its simple and compact cavity design. [4,5] In recent years, novel two-dimensional (2D) materials, such as saturable absorbers (SAs) such as graphene, topological insulators (TIs) and transition metal dichalcogenides (TMDs), [6−10] have attracted researchers' attention because of their unique photonic and optoelectronic properties. Using these materials, hundreds of ns-level pulses have been achieved, which indicates the great potential of 2D materials for 1 µm pulsed lasers.…”

Silver nanorods absorber for passively Q-switched Nd,Gd:CaF2 laser

“…), with the unique advantages of low refractive index and thermal lens effect, spontaneous long fluorescence lifetime, and good thermal stability, have special value applications in the field of solid lasers. Particularly, the AeF 2 − LnF 3 − NdF 3 (Ln: Y 3þ , Lu 3þ , La 3þ , Gd 3þ ) disordered crystals have excellent laser outputs [19,[25][26][27][28][29][30][31][32][33][34] . The addition of non-optically active ions (Y 3þ , Lu 3þ , La 3þ , Gd 3þ ) could effectively relieve the pernicious concentration of quenching, and significantly improve their absorption, emission, fluorescence lifetime properties, and their laser performance [26,27] .…”
