FIGURE 1. The double-nested OPO or NesCOPO used in the VHR-TL broad-tuning-range source uses double-pass pumping (blue) and two different resonant cavities for the signal (green) and the idler (red).

Photonics Applied: Optical Sensing: OPO-based optical analyzer monitors multiple gases in real time

A new gas analyzer based on a compact doubly resonant optical parametric oscillator pumped by a pulsed laser can monitor multiple gases in real time with a very wide dynamic range...
