Study of the laser performance of a novel mixed Nd:Y_0.8Lu_0.2VO₄crystal

Abstract

We present for the first time a diode end-pumped acousto-optic (AO) Q-switched Nd:Y0.8Lu0.2VO4 crystal laser with a comparative planar-planar cavity in this paper. The maximum continuous wave (CW) power of 5.61 W is achieved at the incident pump power of 13.07 W with 20% transmission for the output coupler, resulting in an optical-to-optical conversion efficiency of 43%. For Q-switching operation, at the incident pump power of 13.07 W and 1 kHz repetition rate, the shortest pulse width of 11 ns is measured and the highest peak power of 225.45 kW is obtained for the output transmission of 50%. At 100 kHz repetition rate and 20% output transmission, the maximum average output power of 4.23 W is reached.

Experimental study on doubly QML Nd:Lu0.15Y0.85VO4 laser with AO modulator and central SESAM

“…In order to improve the performance of 1 The article is published in the original. lasers, the double mixed Nd:Gd x Y 1 -x VO 4 , Nd:Lu x Gd 1 -x VO 4 , and Nd:Lu x Y 1 -x VO 4 crystals have been successfully grown and extensively studied as gain media for all solid state picoseconds pulse source [17][18][19][20]. Due to the inhomogeneous broadening in the fluorescence spectra, these double mixed crystals have much broader fluorescence line width than the single vanadate crystals such as Nd:GdVO 4 , Nd:YVO 4 , and Nd:LuVO 4 [9,[12][13][14].…”

Actively Q-switched performance of a mixed crystal Nd:Lu0.5Y0.5VO4 at 1.34 μm

“…Neodymium (Nd) doped mixed vanadate crystals such as Nd:Gd x Y 1 -x VO 4 and Nd:Gd x Lu 1 -x VO 4 have drawn more interests in the fields of high peak power Q switching and mode locking lasers due to moderate stimulated emission cross section and larger fluores cence bandwidth [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Recently, a novel mixed crystal Nd:Lu x Y 1 -x VO 4 was grown by Fuzhou Univer sity and its continuous wave (CW) and Q switched operation at 1064 nm has been demonstrated success fully by our group.…”

Continuous wave Nd:YAG-BiBO blue laser under direct 869 nm pumping

“…Coherent CW light sources in the visible spectral range have become interesting for many technical applications in medicine, display, and other areas [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. An all solid state laser in the blue spectral region is of special interest for high density optical storage, laser based display devices and Raman spectroscopy.…”
