Degenerate type I nanosecond optical parametric oscillators

Smith, A.V.; Armstrong, Darrell J.; Phillips, Mark C.; Gehr, Russell J.; Arisholm, Gunnar

We present numerical modeling and laboratory studies of degenerate type I nanosecond optical parametric oscillators. Because the signal and idler waves are identical and parametric gain is phase sensitive, their round-trip phase is a critical parameter. We show that signal spectrum, transverse mode, and conversion efficiency are all strongly influenced by this phase. We also examine the influence of signal-wave injection seedine and phase-velocity mismatch. © 2003 Optical Society of America.
