Paper Abstract

The power of laser emission is very important for Doppler velocimeters. Doppler velocimeters with high power laser allow us to investigate structure of shock and detonation waves in a nanosecond region and to perform multichannel diagnostics. Two types of single mode lasers are described in this work. High power iodine laser (equals 1.315 micrometers ) of about 2 kW power and impulse duration of about 5 - 10 microsecond(s) . Ruby laser of 150 W power and of 200 microsecond(s) impulse duration. The width of spectral emission is 3.10-3 cm-1 for both lasers. Two interferometer systems, based on these lasers were made: Fabry-Perot interferometer and ORVIS. Also this paper describes the examples of application of interferometer systems with powerful lasers.
