A speed measurement system utilizing an injection-seeded Tm:YAG laser

Abstract

A speed measurement system utilizing a stable single frequency Q-switched Tm:YAG laser was presented in this study. The maximum pulse energy of the laser was 2.38 mJ with the pulse repetition rate of 100 Hz. Using the speed measurement system, the revolving speed of a rotating target could be measured by optical heterodyne detection technique and the maximum measurement error was 0.68 m/s.

Keywords
