High pulse energy and symmetrical far field from an optical parametric oscillator in the red spectral range
(2011)
Red pulses with >30 mJ energy and <0.6 nm bandwidth have been demonstrated using a type 2 phase matched optical parametric oscillator pumped at 532 nm. A symmetrical signal beam with beam diameter-divergence product of ~3 ...
Optimal classification of standoff bioaerosol measurements using evolutionary algorithms
(2011)
Early warning systems based on standoff detection of biological aerosols require real-time signal processing of a large quantity of high-dimensional data, challenging the systems efficiency in terms of both computational ...
Sum-frequency generation of high-energy and hig-beam-quality ultraviolet pulses
(2011)
Sum-frequency generation of UV pulses exceeding 25 mJ and with beam quality has been demonstrated by mixing the third harmonic pulses of a flash lamp pumped 1.06 μm Nd:YAG laser with 1.7 μm pulses from an optical parametric ...
