With a spectral transmission band extending to 5um, and an effective non-linear coefficient in excess of 14pm/V, new applications for MgO:PPLN are growing rapidly. Configuring MgO:PPLN as an OPO can enable idler powers in excess of several Watts, ideally suited for: laser countermeasures, LIDAR, remote spectroscopy and environmental monitoring.
The combination of uniform vertical domains and a crystal aperture of 3 x 1mm increases resistance to damage ensuring reliable operation under the most extreme conditions. With damage thresholds exceeding 250MW/cm2, and a large range of poled periods as standard, these crystals are now commonly utilised in 1064nm pumped countermeasure systems all over the world.
Our guide to PPLN explains the basic theory behind nonlinear processes as well as providing practical information on PPLN usage to help you gain the best efficiency from our crystals.
OPO crystals for are available off-the-shelf and in various lengths over a wide temperature tuning range.
