“…A similar relationship is observed in Fig. (7), when the pump power increases, we can see that the beam size at the waist decreases. The Gaussian pump beam remains the same shape as it propagates from 0 to "∞", at lower pump powers.…”

In this paper, we present a method for active control of thermally induced lensing in high-power lasers. We used thermal lensing to study the advantages of high-power lasers. Many delivery optics are sensitive to the thermally induced lens, which can change the focus position of the transmitted beam. To compensate for this, we used thermal lensing by pumping a crystal that had no absorption or amplification at the seed beam wavelength. By controlling the strength of the heat source, we demonstrate acute control of the focus position. Our modelling work is based on the finite-volume method (FVM) to analyse thermal effects in end-pumped solid-state crystals. This work has the potential to pave the way for active control of a thermally induced lens in high-powered laser-based applications.

“…Laser sources working in the UV, near-infrared, and midinfrared ranges have shown their important role in many practical applications such as atmospheric and solar guidance, free-space communication, detectors, and others. [1][2][3][4][5][6][7] Therefore, many nonlinear optical crystals have intensively been studied and developed to produce laser sources of these ranges. 3,[8][9][10][11][12] Among these materials, special attention has been paid to those which can effectively convert the 1.060-1.064 mm emission from commercially available laser medium sources such as Nd:YAG, Nd:Cr:YAG, Nd:YLF, Nd:YVO 4 , and Nd:YCO.…”
