Strongly Correlated Atomic Oxygen Lasing In Air With Nanosecond Pumping
- View All
Investigation of the fast-time behavior of atomic oxygen lasing in the forward and back- ward direction in air is undertaken. Fast photodiodes and a 20 GHz oscilloscope were used to characterize the time history of the ultraviolet pump beam at 226 nm for single laser shots along with the forward and backward generated atomic oxygen lasing at 845 nm. Strongly correlated emission in the forward and backward directions is shown to be driven by oscillations in the ultraviolet pump pulse, consisting of a series of short duration (<30 ps) pulses emitted in both the forward and backward directions. This characterization study pushes towards the application of the remote oxygen lasing in air for remote sensing applications. © 2012 by Princeton University.
