S. Slyusarev et al., INFLUENCE OF ELECTROCHROMIC DAMAGE OF A KTIOPO4 CRYSTAL ON A PHASE-LOCKED CW OPTICAL PARAMETRIC OSCILLATOR, JPN J A P 1, 35(6A), 1996, pp. 3459-3460
The influence of electrochromic damage on a phase-locked cw doubly res
onant optical parametric oscillator (OPO) was examined for KTiOPO4(KTP
) crystals grown by three different methods. The damage occurred at a
relatively low E-field of similar to 3V/mm. Additional thermal feedbac
k control was effective to reduce the E-field necessary for the phase
locking for long-term operation.
