Frequency Stabilization of Semiconductor Lasers | SpringerLinkThe frequency stabilization involves basically three parts: a reference frequency, i.e., the target frequency the laser frequency is to be locked, a frequency discriminator, and a method of feedback to tune the laser. The absorption lines of atoms or molecules are mostly often used references, especially for applications of laser spectroscopy.

Laser arrangement with frequency stabilized and intensity ...

In a laser in which two longitudinal modes of a laser emission are excited, high frequency stability and intensity stability of the laser emission are achieved in that the dimensioning of the laser is used to produce a coupling of the intensities of the two modes and thus at least one minimum of the gain curve over frequency appears.

Optical Cavities for Laser Stabilization | NIST

A well-designed lock can reduce the residual frequency noise of the laser to that of the thermal noise floor of the optical cavity. This technique can lead to laser linewidths of 100 mHz and below. To reach such performance levels it is necessary to isolate the reference cavity from vibrations and thermal fluctuations.

Abstract. A new method of laser frequency stabilization using polarization property of an optical cavity is proposed. In a standard Fabry–Perot cavity, the coating layers thickness of cavity mirrors is calculated to obtain the same phase shift for s- and p-wave but a slight detuning from the nominal thickness can produce s- and p-wave phase ...
