Summary:Self-injection locking of a laser diode to a high-Q whispering gallery mode (WGM) microresonator proved to be a simple an effective way of laser stabilization. The Rayleigh backscattering provides a fast passive feedback at WGM frequency [1] , [2] . Pumping of WGM by a diode laser self-injection locked (SIL) to the resonator allows to achieve a Kerr soliton frequency comb generation [3] , [4] .
