Abstract

In order to effectively design high-power nonlinear wavelength conversion devices, one requires accurate knowledge of the thermo-optic coefficients (dn/dT) for the nonlinear materials of interest. The thermo-optic coefficients derived or measured can be verified for a particular spectral region by measuring the wavelength dependent temperature bandwidth for harmonic conversion. We report lithium triborate (LBO) temperature bandwidths, which result from temperature-tuned data for Ti:sapphire laser second-harmonic generation (SHG) in the 0.75-0.9-µm wavelength region. Comparisons were made between our measured results and throe calculated from thermo-optic data2 obtained at room temperature.
