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...

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...
