A direct method of observing the wavelength versus time of modulated single-mode GaAlAs lasers is described. The method uses a grating spectrometer and an avalanche photodiode and achieves resolutions of 0.01 A and 1 ns. Although the laser consists o

Experimental Kodak 4-Z emulsion hypersensitized to infrared radiation has been successfully used for low spatial frequency off-axis holographic recording of a Nd-glass pulsed laser wavefront. The holographic recording system used was a modified Mach-

The elastic properties of single‐crystal grains in polycrystalline material can be studied through Brillouin scattering using a laser probe beam. The Brillouin spectra of hot‐pressed CaF2 (Irtran‐3), having a typical grain size of 150 μm, is p

Local reference beam holography can be used in conjunction with interferometry to determine the complex amplitude distribution in the output of CW and pulsed laser beams. A hologram is recorded of the laser wavefront with a locally generated referenc

A single-mode optical liner can De used as a leg of an interterometer, making possible new applications of interferometry. Since this kind of fiber does not allow higher-order modes to propagate, it acts as a spatial filter and provides a smooth wave

The key elements in fabricating stable coherent array of lasers are (1) a suitable phase reference, (2) selection (discrimination) of one single array mode out of a closely spaced multitude of eigensolutions. We describe several approaches including
