Laser Doppler velocimeter on the base of high-power iodine and ruby lasers

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.
