Frequency stabilization at the kilohertz level of a continuous intracavity frequency- doubled singly resonant optical parametric oscillator

摘要

A continuous intracavity frequency-doubled singly resonant optical parametric oscillator (OPO) is stabilized to thenside of the transmission peak of a mediumfinesse Fabry–Perot cavity. The narrow bandwidth of the frequency noisenof this OPO allows this simple scheme to lead to a stability of a few kilohertz with respect to the locking etalon. Thensystem, operating in the visible domain, remains locked for more than 1h. © 2010 Optical Society of America
