“…For pump wavelength of 1047 nm we have solved numerically the equations (6). For noncritical phase matching, for collinearly propagating waves in the x-z plane in KTP along the x axis, for the polarization of the pump and signal waves along the y axis and idler one along z axis the solution in function of pump wavelength is shown in Fig.1.…”

We report on a passively Q-switched end pumped Nd:YLF laser including a noncritically phase-matched KTP singly resonant intracavity optical parametric oscillator (IOPO-KTP). For the Q-switching operation we have used Cr:YAG saturable absorber. The optimized passively Q-switched Nd:YLF laser without IOPO generated linearly polarized pulses of 11.5 ns and 1.07 mJ at 1047 nm. The conversion efficiency of the optimized Q-switched pulse energy at 1047 nm to 1547 nm of signal approached about 47%. For optimizing both Nd:YLF laser and IOPO we have numerically solved theoretical model. We have achieved 1.6-ns duration pulses at 1547 nm with energy of 0.5 mJ and peak power above of 300 kW. The beam quality was excellent (M 2 ≈1).

“…These glass materials have also been used for optical fibers [1], waveguide lasers [2], optical amplifiers [3], optical devices for multicolor light emission [4,5], solid state lasers [6], mid-infrared lasers [7], and Qswitched devices [8]. Among rare earth ions doped glasses, Tb 3+ -doped silicate glasses have been extensively investigated since they possess high luminescence intensities.…”

“…It is well known that phosphate glasses are suitable rare-earth host materials because they have a very high solubility for rare-earth ions [3]. Trivalent erbium-ytterbium codoped phosphate glasses are thus one of the most popular materials for laser oscillators and amplifiers operating at an eye-safe wavelength region near 1.53 m [4,5]. Spectroscopic properties of materials, such as the absorption and luminescence spectra, the lifetimes of excited states, and the radiative quantum efficiency, etc., are becoming important and useful in order to understand and improve photonic device performances.…”
