Second harmonic generation at 515 nm in RTP with temperature insensitive and non-critical phase-matching (poster)
Abstract : We demonstrate that around 1030 nm, RbTiOPO4 (RTP) realizes the second harmonic generation of Yb-doped lasers in non-critically phase-matched configuration at ambient temperature, with efficiencies comparable to LBO and wide thermal acceptance. Frequency doubled lasers are widely used in today's industry, from micromachining to solid-state pumping or spectrometry applications. While it is a nonlinear process fully mastered today, with conversion efficiencies routinely reaching more than 60%, it is still a technique sensitive to many outside parameters such as angular misalignments or temperature operation. In order to increase the robustness of a frequency conversion scheme, one needs to reduce the dephasing between the fundamental and the second harmonic caused by either an angle misalignment (angular sensitivity) or a temperature change (thermal sensitivity).
