Combined frequency comb and continuous wave cavity-enhanced optical-optical double-resonance spectrometer in the 1.7 $\mu$m range

Vinicius Silva de Oliveira, Adrian Hjältén, Isak Silander +4

We present an optical-optical double-resonance (OODR) spectrometer based on a 3.3 $\mu$m continuous wave pump and two cavity-enhanced probes: a frequency comb tunable in the 1.64 - 1…
