Phase-matching free pulse retrieval based on plasma-induced defocusing [PDF]

EPJ Web of Conferences, 2023
A phase-matching free pulse retrieval technique based on plasma-induced defocusing in a rare gas is presented. Based on a pump-probe setup, this technique uses a moderately intense pump laser pulse for ionizing the medium, creating in turn an ultrafast ...

A tunable far infrared laser [PDF]

IEEE Journal of Quantum Electronics, 1984
A continuously tunable far infrared (FIR) laser has been demonstrated; experimental results are presented. A high-pressure (10-12 atm) continuously tunable CO 2 TE laser is used to pump Raman transitions in CH 3 F; the generation of continuously tunable radiation in the 250-300 \mu m wavelength range is reported.
