The Copper Vapor Laser (CVL) has been with us only a few years, but has demonstrated its potential as a high repetition rate strobe for high speed imaging. It has extended the capabilities of high-speed recording equipment by providing intense light and ultrashort pulses to help image events that might have otherwise been lost.
