ABSTRACT
For the purpose of optically cooling, trapping, detecting and accelerating Cesium atoms in a "fountain clock", semiconductor lasers with external resonator have been designed, built and tested in their spectral characteristic and their long-term frequency drift.

Multiple Quantum Well lasers with AR coating on one end face and a...

An experiment demonstrating the principle of mode recognition has been performed. In the experiment, a He-Ne laser with phase synchronized TEMo1 mode is used. This laser has two stable (bistable) states corresponding to be emission of a right- and left- hand helical waves. Injection of light of one state can...

ABSTRAK
The principles of frequency stabilization are to keep constant the optical path length in laser cavity by controlling the laser tube length. In this system used temperature servo control to control the laser tube length.

As reference to an error derived by a sensitive frequency discriminator. Basically the operation...

ABSTRACT
Observation of fluorescence decay signal of condensed-state molecular samples in the time domain has proved very useful for its identification and analysis. In order to overcome the noise problem in the generally weak fluorescence signals a double-gated boxcar integrator has been designed and incorporated into a spectrometer. The design concept...
