Taking advantage of some of unique optical properties of crystal materials, we explore use of crystalline whispering gallery mode resonators for lasers and nonlinear optics. In this talk, I will discuss some of the recent works in laser frequency stabilization, SHG and comb generation, and low threshold UV laser.
