High resolution michelson interferometer for spectral investigations of lasers
Applied Optics
|February 2, 2010
Abstract:
An extremely stable Michelson interferometer with an optical path difference up to several thousand meters has been developed for the precise investigation of the frequency behavior of lasers. The theoretical value for the spectral resolution is of the order of 10(12). The spectral resolution of a real system is determined by external disturbances and was measured to be close to 10(1l). The capability and the characteristics of the system are discussed.

01:25IR Spectrometers
There are two main infrared (IR) spectrophotometers: dispersive IR spectrometers and Fourier transform infrared (FTIR) spectrometers. In a dispersive IR spectrometer, a beam of infrared radiation produced by a hot wire is divided into two parallel equal-intensity beams using mirrors. One beam passes through the sample, while another is a reference beam. The beams then move through the monochromator, which separates the radiations into a continuous spectrum of different frequencies. The...
01:26Raman Spectroscopy Instrumentation: Overview
A conventional Raman spectrophotometer includes a laser source, a sample holding system, a wavelength selector, and a detector.
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
