Abstract
A photodiode-operational amplifier circuit is described, with which the shot-to-shot energy variations of a pulsed laser system can be monitored. The system has a useful sensitivity over the wavelength range 330-1100 nm; this is sufficient, with suitable focusing optics, to monitor laser pulses of total energy as small as 1 nJ. The system is insensitive to ambient light conditions.Keywords
