Abstract
Spectral hole burning laser frequency stabilization in Eu3+:Y2SiO5 is performed in a cryogenic environment with high temperature stability and low levels of vibration. Several properties of Eu3+:Y2SiO5 spectral holes are measured, including magnetic field shifts, inhomogeneous broadening of the hyperfine structure, and frequency shifts due to optical probe power. A precise calibration of a temperature insensitive point is also performed, where the temperature-induced frequency shift is canceled to first order by the pressure-induced shift from the crystal's helium gas environment.
