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.

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.

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.

We describe an erbium-fiber laser frequency comb that supports optical frequency synthesis at the millihertz level, or fractionally as 3×10 −18 τ −1/2, by ensuring all critical fiber paths are within the servo-controlled feedback loop.
A linear polarizer or Brewster plate is placed inside the reference cavity, so that the reflected light acquires a frequency-dependent elliptical polarization. A simple polarization analyzer detects dispersion shaped resonances which can provide the error signal for electronic frequency stabilization without any need for modulation techniques. 关键词：

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 ...

Elliptical polarization is incorporated into the optical path so that the change in polarization that occurs when the frequencies coincide may be detected to provide a feedback signal to ...
