Paper Abstract

We review progress on quasi-phasematched optical parametric oscillators (OPOs) in bulk periodically poled LiNbO3. We have extended the electric-field poling process so that we now reliably fabricate crystals over 60-mm long in full 3-inch-diameter, 0.5-mm-thick wafers. Periodically poled material retains the low loss and bulk power handling properties of single domain LiNbO3, and QPM allows noncritical phasematching with the highest value of the nonlinear coefficient. OPOs pumped by 1.064-micrometers Nd:YAG lasers have been operated over the wavelength range 1.36 micrometers to 4.9 micrometers with tuning by temperature or QPM period. We have shown oscillation threshold as low as 0.006 mJ with a Q-switched pump laser, and pumping over 25 times threshold without damage. We have also demonstrated a doubly resonant OPO pumped directly with a commercial cw diode laser at 978 nm, and a 1.064-micrometers -pumped cw singly-resonant OPO with threshold < 3 W.
