Investigation of the spectral and energy characteristics of a pulsed optical parametric oscillator operating in the regime of external signal injection
Abstract
Experimental and theoretical investigations were made of the operation of a singly resonant optical parametric oscillator made of a lithium niobate crystal and pumped by the fundamental-frequency radiation from a YAG:Nd laser. An external signal was injected into the oscillator. When the source of this signal was another optical parametric oscillator utilizing a crystal of barium sodium niobate, it was possible to generate narrow-band radiation throughout the tuning range of the singly resonant lithium niobate oscillator: the output power obtained in this case was several times higher than that in the absence of injection and the spectral brightness of the radiation was 1000 times higher. This was achieved at the expense of a slight loss (less than 10 percent) of the fundamental-frequency radiation used to pump the barium sodium niobate oscillator.
