We utilize highly sensitive spectroscopic local temperature probe to ascertain cooling performance of Yb:YLF crystal as a function of wavelength and temperature. A minimum achievable temperature of 120 K is measured at pump wavelength corresponding to E4-E5 Stark manifold transition. Results verify current model for laser cooling cycle as well as demonstrate the lowest temperature achievable by means of optical refrigeration to date.
