Description
Summary:A technique to synchronize multiple copper vapour laser (CVL) systems in master oscillator power amplifier configuration to obtain long-duration power stability is discussed in this manuscript. The technique utilizes optoelectronic interconversion of the current pulses of CVL oscillator and amplifiers units as a feedback signal. The signal processing of the current pulses was performed using a monostable multivibrator, R–S flip-flop and passive low pass filter. The DC voltage generated corresponding to the quantum of temporal mismatch between the oscillator and the amplifier modules is sampled, averaged and compared to the set point voltage using a Programmable Logic Controller. The timing signal of the respective amplifiers could be accordingly adjusted to synchronize with the CVL oscillator optical pulses to obtain long-duration power stability.
