Here we report on measurements made with an improved CO2 Sounder lidar during the ASCENDS 2014 and 2016 airborne campaigns. The changes made to the 2011 version of the lidar included incorporating a rapidly wavelength-tunable, step-locked seed lase

We have measured the column-averaged atmospheric CO2 mixing ratio to a variety of cloud tops by using an airborne pulsed multi-wavelength integrated-path differential absorption (IPDA) lidar. Airborne measurements were made at altitudes up to 13 km

Publikováno v: Physical Review B. 59:15740-15747

The coherent response of excitons and low-energy continuum excitations has been determined in InP at 5 K using spectrally resolved four-wave mixing employing 40 fs pulses in a self-diffraction geometry. The excitons were studied under simultaneous ex
