An upper limit to the frequency noise associated with the relaxation oscillation of a monolithic Nd:YAG ring laser

A measurement of the frequency noise at the relaxation oscillation frequency of a Nd:YAG monolithic non-planar ring laser is presented. By careful monitoring of various applied calibration signals, a limit to the frequency noise level of ∼ 6.3 × 10 −2 Hz/√Hz is set over the relaxation oscillation ba...

Description
Summary:A measurement of the frequency noise at the relaxation oscillation frequency of a Nd:YAG monolithic non-planar ring laser is presented. By careful monitoring of various applied calibration signals, a limit to the frequency noise level of ∼ 6.3 × 10 −2 Hz/√Hz is set over the relaxation oscillation bandwidth and it is shown that this is approximately at the level to be expected, based on the relaxation oscillation induced time varying refractive index.
