Photopyroelectric spectroscopy (PPES) was used in a novel non-contact experimental configuration to obtain, for the first time, high-resolution absolute spectra of the optical-to-thermal energy conversion efficiency (non-radiative coefficient), ηNR(λ), of Ti : Sapphire laser crystals with widely different figures of merit. These spectra were found to depend on the optical quality of the bulk and of the polished surfaces of the Ti : Sapphire material
