532 nm continuous wave mode-locked Nd:GdVO₄laser with SESAM

Abstract

Abstract:We obtain continuous wave mode-locked Nd:GdVO 4 -KTP laser with a SESAM. This is the first report of CW modelocked Nd:GdVO 4 -KTP laser with a SESAM to our knowledge. 396 mw CW mode-locked pulse is achieved at the incident power of 7.653 W, with the repetition about 95 MHz. The pulse duration is assumed to be 5.5 ps, this is the shortest green pulse of 532 nm with SESAM.

High electrical-to-green efficiency high stability intracavity-frequency-doubled Nd:YAG-LBO QCW 532 nm laser with a straight cavity

“…In our opinion, three factors limit the efficiency: astigmatism loss induced by the concave foldmirror [7,8,[11][12][13], relatively low transmittance at 532 nm and reflection at 1064 nm of the dichroic fold-mirror, difficulties in adjusting the complex system. In order to avoid the above factors limiting the efficiency, we adopted a straight cavity introduced in [14,15].…”

Continuous-wave Nd:GdVO4/LBO laser at 541.5 nm under diode pumping into the emitting level

“…Another vanadate crystal, Nd:GdVO 4 , which was confirmed to be supe rior to Nd:YVO 4 in thermal properties, was also inves tigated extensively. The research to output wavelengths involving Nd:GdVO 4 crystals were mostly focused at 1063 nm [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30], 1341 nm [31][32][33][34][35][36][37], and 912 nm [38][39][40][41][42][43]. However, through the analysis of a spectroscopic study has demonstrated that there are three or four emission bands on the F 3/2 -I 11/2 transition of Nd:GdVO 4 crystal.…”

Broadband single-walled carbon nanotubes absorber for solid-state ultrafast lasers

“…Since semiconductor saturable absorber mirrors (SESAMs) were successfully developed two decades ago [1], they have been widely used for ultrashort pulse generation in passively mode locked solid state lasers [2][3][4][5][6][7]. However, SESAMs have encountered two major practical concerns such as the short operation wavelength range and the high cost.…”
