Temperature distribution and stress analysis of end pumped lasers under Gaussian pump profile

Effects of pumping profiles on the temperature distributions in doubleend pumped solid-state lasers: A comparison study

“…Under the Gaussian pump profile where n=2 and for the same laser parameters, the obtained results perfectly match a previous work presented by Ref. [17].…”

“…To assess our proposed model, we make a comparison with an earlier analytical work presented by Refs. [16][17]. The heat loading and the radial temperature distribution had been modeled using Nd: YAG as an active medium.…”

“…For the same laser parameters listed by Ref. [17], the maximum temperature of 295.5 K and 225.9 K were obtained on both rod end faces. For n much greater than two, which tend to a top-hat profile, the temperatures gradient between the center and surface of the laser rod were shown in figures 3c,d.…”

“…By taking into account thermal conductivity as a function of temperature, the analytical thermal model for the double-end laser diode pumped cylindrical laser rod was derived by solving the heat equation. Also, the temperature distribution and the thermal stresses were estimated under top-hat and Gaussian pump beam profiles by Refs [16][17][18]. With complicated boundary conditions utilizing COMSOL Multiphysics simulation software, the thermal model of a slab crystal was investigated.…”

Preparation of LiNbO3 nanoparticles by green synthesis laser ablation in water

“…Because of its excellent piezoelectric, electrooptic, non-linear optical, and acousto-optic properties [10][11][12], LN is regarded as a crucial ferroelectric material that is widely used in optical switches, optical telecommunications, and second harmonic generation imaging probes [13][14][15]. Nanomaterials of lithium niobate have been prepared by various methods, for instance, sputtering [16][17][18], molecular beam epitaxy (MBE) [19][20][21], MOCVD [22][23][24], sol-gel method [25][26][27], spin coating [28][29][30], PLD [31][32][33], wet-chemical [34][35][36], and solution-phase [37][38][39]. Due to its simplicity, cost-effectiveness, one-step process, lack of catalyst requirements, high purity, and good control over the size and morphology of the nanoparticles, laser ablation of nanoparticles in a liquid medium is considered one of the most interesting and promising routes [40][41][42][43][44].…”
