“…However, not all nonlinear media are suited for high powers of the second harmonic (SH) because of adverse effects such as photochromism [2,3], photorefractivity [4] or thermal dephasing due to absorption [3,5,6].…”

“…But the conversion efficiency of these materials (poled or not) was strongly degraded when exposed to incident fundamental powers of multiple tens of watts (e.g., [7][8][9][10]). In high-power experiments it is therefore beneficial to use nonlinear crystals with higher tolerances to optical power and place them inside an optical resonator (cavity) with sufficiently high finesse to compensate for their smaller d eff .…”
