Abstract
The principle of pump noise suppression is applied to a Nd:YVO4 microchip l aser, optically pumped by laser diodes. The noise of the microchip laser at low frequency (below the relaxation oscillation frequency) is compared for noisy and amplitude squeezed laser diodes. The minimum intensity noise of the microchip laser is 7 dB above SNL at a frequency of 40 kHz. Very good a greement between experimental results and theoretical predictions of a mode l based on quantum Langevin equations is found.
