Abstract

The Copper Vapour Laser (CVL) is an efficient ("1%) source of pulsed high power visible laser light in the green (511nm) and yellow (578nm) region of the spectrum. We present results which characterise the performance of a three laser CVL system designed to produce over 90w of visible power with 90% of this output having a full angle divergence of less than 400 microradians. The total output power and output power within 400μ radians of an Injection Controlled Oscillator (ICO) have been measured as a function of injection timing. The power extracted from a 60W lasers (CU60) acting as a single pass amplifier was also mecLs,..veci as a function of its timing. Laser pulse shapes of the total output and within 400 μ rads are shown both for the ICO and the entire system. Measurements have also been made of the small signal gain and saturation fluence by probing with narrow beams both at the edge and on the axis of the final amplifier stage of the system.
