OPO based on Nd³⁺:YAG lasers have a number of advantages compared to analogues:
* the possibility of implementing the OPO operation in the traveling wave mode through the use of a ring resonator, which makes it possible to eliminate the pump radiation feedback between the Nd³⁺ laser and the OPO without the use of additional measures;
* the possibility of using a circuit solution in the case of a linear OPO resonator (standing wave mode), which allows eliminating feedback on pump radiation without the use of expensive Faraday isolators;
* completely solid-state approach.
