Doubly resonant optical parametric oscillator:
a generic transmitter architecture for DIAL,
Myriam Raybaut 1 , Antoine Godard 1 , Ajmal K.

The French Aerospace Lab, France. Entangled cavity
doubly resonant optical parametric oscillators are
able to provide high peak power, single longitudinal
mode emission, with wide tuning range and
high frequency stability, which make them well
suited for multi-specie DIAL.
