LD-pumped Nd:GdVO4 Raman laser at 1166 nm with LiIO3 crystal

Abstract

Abstract:We demonstrated an all solid-state Nd:GdVO 4 Raman laser using LiIO3 as Raman crystal. The maximum output power of 0.645 W was obtained at 1166 nm, corresponding to the conversion efficiency of 8.5%. The Raman laser generated pulse width of 1166 nm as short as 9 ns, which was about four times shorter than that of fundamental light of 1.06 μm. The maximum pulse energy of 62 μJ and the highest peak power of 5.1 kW were achieved with pulse repetition frequency of 5 kHz. Pulse energy versus incident pump power

High-efficient diode-pumped passivelyQ-switchedc-cut Nd:GdVO4self-Raman laser

“…In 2010, a diode-pumped actively Q-switched a-cut Nd:GdVO 4 self-Raman laser was reported, and a maximum average output power of up to 2.26 W at 1173 nm was achieved at a pulse repetition frequency of 30 kHz [24]. In 2011, an all-solid-state Nd:GdVO 4 Raman laser using LiIO 3 as the Raman crystal was demonstrated, in which a maximum output power of 645 mW and a conversion efficiency of 8.5% were obtained [25]. Recently a passively Q-switched a-cut Nd:GdVO 4 self-Raman laser with Cr:YAG as the saturable absorber was reported, and a maximum average output power of 204 mW, a pulse width of 1.8 ns and a repetition rate of 27.5 kHz at 1173 nm were obtained at the maximum incident pump power of 10 W [26].…”

Investigation on the bulk growth of $${\upalpha }$$ α - $$\hbox {LiIO}_{3}$$ LiIO 3 single crysta

“…Its wide transparency range from 300 nm to 5 μm is very interesting for applications in the infrared range [3]. In addition, some new applications in the fields of Raman laser, optical data storage have been reported [9][10][11][12] and permanent optical waveguides produced by proton implantation in α-LiIO 3 crystals were studied [13]. By considering the significant technological application of the material, the growth of α-LiIO 3 has been performed by many authors.…”

Stimulated rotational Raman scattering at multiwavelength under tea CO2 laser pumping with a multiple-pass cell

“…Raman effect is widely used for frequency shift of laser radiation [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. By using stimulated rotational Raman scattering (SRRS) of CO 2 laser radiation, coherent far infrared (FIR) radiation can be gener ated efficiently, which is necessary for laser photo chemistry, remote sensing and laser isotope separation of UF 6 [17][18][19][20].…”
