Spatiotemporal control of two-color terahertz generation
Tanner T. Simpson, Jeremy J. Pigeon, Manfred Virgil Ambat +5
A laser pulse composed of a fundamental and properly phased second harmonic exhibits an asymmetric electric field that can drive a time-dependent current of photoionized electrons.…
Resonant noninear refraction of 4-5 m light in CO and CO gas
Jeremy Pigeon, Dana Tovey, Sergei Tochitsky +7
The resonant nonlinear refraction of 4-5 m light in CO and CO gas at a peak intensity of 15 MW/cm was demonstrated using time- and frequency-resolved measurements of sel…
Lasing in 15 atm CO2 cell optically pumped by a Fe:ZnSe laser
Dana Tovey, Jeremy Pigeon, Sergei Tochitsky +7
10 μm lasing is studied in a compact CO2-He cell pressurized up to 15 atm when optically pumped by a ~50 mJ Fe:ZnSe laser tunable around 4.3 μm. The optimal pump wavelength and par…
High-power, mid-infrared, picosecond pulses generated by compression of a CO2 laser beat-wave in GaAs
J. J. Pigeon, S. Ya. Tochitsky, C. Joshi
We report on the generation of a train of ~ 2 ps, 10 um laser pulses via multiple four-wave mixing and compression of an infrared laser beat-wave propagating in the negative group…
