Simple laser pulse energy monitor.
A simple and inexpensive relative energy monitor for short laser pulses is described. The three basic units of this system are an integrating detector circuit, an amplifier, and a peak detector and hold circuit. With this device one can measure optical pulse energies (at 1.06 microm) as small as 1.0 nJ with an electronic accuracy of approximately 1%.
