Paper Abstract

Although there will always be intensity noise from a laser diode due to quantum effects, current fluctuations from the laser controller add additional noise. Noise spectra in the 0 - 150 MHz frequency range is presented for cw lasers powered by commercial controllers as well as by a simple, but well shielded battery supply. Various examples also are given to show the sensitivity of the noise level of the laser to small changes in wiring and grounding configurations. The laser diode user gains a familiarity with the magnitude of the intensity noise in this frequency range.
