“…A well known representa tive is Nd:YVO 4 , which has been widely used both in research and commercial devices. 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 [22][23][24][25][26][27][28][29][30][31][32]. A more efficient pumping method was presented recently, which was to pump the Nd 3+ ions directly into the 4 F 3/2 upper lasing level.…”

A high efficiency Nd:GdVO 4 bounce laser in band pumped at 879 nm is demonstrated for the first time. From a side pumped Nd:GdVO 4 crystal, 8.2 W output was obtained with 18.5 W absorbed pump power. Corresponding slope efficiency with respect to the absorbed pump power was 51.4%, and the beam quality factor M 2 is 1.13 and 1.15 for tangential direction and sagittal direction, respectively. Effects of crystal's dop ing concentration and temperature on laser power and conversion efficiency were also investigated.

“…c ∨ The crystal of Nd:YLF has the advantages of long fluorescence life, small nonlinear refractive index and high damage threshold. Moreover, the natural double reflection of Nd:YLF is much bigger than its thermally induced birefringence, which can eradicate thermal depolarization of the optical isotropic matrix materials such as Nd:YAG, Nd:YVO 4 , and Nd:GdVO 4 [9][10][11]. Therefore, Nd:YLF has a great superiority in effective energy storage, Q switch output, single mode stability and in the application of ultrafast laser system [12][13][14][15][16][17][18] [20].…”

In this paper, we describe a Nd:YLF laser based on high speed RTP electro optical cavity dump ing technique. Two home made 150 W fiber pump modules are used from both sides to pump Nd:YLF crystal. Coupling systems are the key elements in end pumped solid state lasers, the aberrations of which greatly affect the efficiency of the lasers. In order to get high efficient and good quality laser output, the optical soft ware ZEMAX is used to design a four piece coupling system. When the pumped energy is 32 mJ at the repe tition rate of 1 Hz, the output energy is 6.5 mJ with 2.5 ns pulse width. When the pumped energy is 13.1 W at the repetition rate of 200 Hz, the output energy is 2.2 W with small M 2 factor where is 1.04, and is 1.05, and the light light conversion efficiency is up to 16.8%.

“…Crystals of rare earth orthovanadates have been used as materials for lasers [1][2][3]. The YVO 4 , GdVO 4 , and LuVO 4 compounds are most interesting for optical applications, because they have no fundamental absorption bands in the visible and ultraviolet spectral ranges [4].…”
