Diode single-end-pumped AO Q-switched Nd:GdVO4 266 nm laser

A compact efficient deep ultraviolet laser at 266 nm

“…To date, one of the common approaches to supplying UV lasers is to utilize the extra-cavity harmonic generation configuration using nonlinear optical conversion [4][5][6][7][8][9][10]. Unfortunately, in order to acquire optimal efficiency and output power, it is necessary to increase the power intensity 5 Author to whom any correspondence should be addressed.…”

303.5 nm cw Pr:BYF–BBO laser emission under 447 nm all-solid-state Nd:GdVO4–BiBO blue laser pumping

“…Diode-pumped Nd-doped crystal lasers operating in the infrared, visible, and UV spectral regions have wide applications in the fields of industry, defense, medical treatment, and scientific research. UV light sources based on nonlinear-optical frequency conversion of solid-state lasers are in high demand for various applications in science and industry because of their compactness, narrow spectral width, and reliability [1][2][3][4][5][6][7][8][9]. In the past 20 years, extensive efforts toward the development of nonlinear-optical crystals have been aimed at producing such a laser by means of frequency conversion of high-power solid-state lasers [10-12, 9, 13-17].…”

The generation of a continuous-wave Nd:YVO4/LBO laser at 543 nm by direct in-band diode pumping at 888 nm

“…A well-known representative crystal is Nd:YVO 4 , which has been widely used in both research and commercial device production. The research on output wavelengths involving Nd:YVO 4 crystals has been mostly focused at 1064 nm [16][17][18][19][20][21][22][23][24][25][26][27], 1342 nm [28][29][30][31][32][33][34] and 914 nm [35][36][37][38][39][40]. However, the analysis of a spectroscopic study has demonstrated that there are three or four emission bands for the F 3/2 -I 11/2 transition of Nd:YVO 4 crystal.…”
