摘要
The influence of dispersion in the active medium and selected resonator elements (Fabry–Perot interferometers) on the output characteristics of a two-frequency diode-pumped Nd:YAG laser has been investigated. It is shown that the presence of the interferometers causes the beat frequency to depend on the generation wavelength. Based on this effect, a method to determine small displacements is proposed. A displacement of the resonator mirror as small as ~40 nm (less than one twentieth of the laser radiation wavelength) has been recorded experimentally.
