“…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, short pulse width, high sta bility and good beam quality of the 1053 nm laser out put is obtained, which can be attributed to the way of LD double end pumped Nd:YLF, cavity dumping technology and excellent four piece coupling system design.…”

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%.

We present modification of difference frequency generator of coherent THz radiation in a nonlinear GaSe crystal using dualwavelength diode-pumped solid-state Nd:YLF laser. Generation at the two wavelengths (1.047 and 1.053 μm) was carried out by equalization of the gains at these wavelengths near the frequency degeneracy of the transverse modes in resonator cavity, Qswitched by acousto-optical modulator. The main parameters of the device were measured: angular synchronism (width 0.6 degrees), polarization ratio (1:100), conversion efficiency (10 -7 ), pulse power (0.8 mW), frequency and width (53,8 сm -1 , 0,6 сm -1 ), pulse width and repetition rate (10 ns ,7 kHz). The method is promising for practical purposes.

The spectral parameters of neodymium ions in anisotropic YLiF4, SrMoO4, PbMoO4, CaMoO4, SrWO4, and BaWO4 crystals with a scheelite structure are experimentally studied in the region of 1 μm. The luminescence spectra of neodymium ions at the 4F3/2 → 4I11/2 transition in these crystals exhibit pronounced polarisation dependences. It is shown that, using different orientations of the active laser element and separating a particular radiation polarisation, one can control the spectral dependence of the active medium gain, switch the laser wavelength, and create dual-wavelength lasers. A dual-wavelength Nd3+ : YLiF4 laser emitting at λ = 1047 and 1053 nm with identical linear polarisations and good temporal and spatial matching is demonstrated.
