Abstract

We present the theory and implementation of various electro-optic feedback systems used to stabilize the intensity of lasers. These variably attenuate the beam and sample the result applying feedback to achieve a desired intensity despite laser fluctuations. In this way extremely stable beams (0. 01 variation) have been produced over the spectral range 257 nm - 10. 6 p. Applications include radiometric calibrations spectroscopy fluorescence-tagged detection laser heating controlled ablation and video disk mastering. Lasers stabilized this way include CW modelocked and Q-switched pulsed Nd:YAG Ar ion (both the fundamental and the second harmonic) C02 Ti:Sapphire He-Ne and He-Cd.
