Abstract: The system and method of using an ultra-short pulse mid and long wave infrared laser. The system is seeded with a 2 μm laser source having a pulse duration in the femtosecond range. The beam is stretched, to increase the pulse duration, and the beam is amplified, to increase an energy level of the laser beam. Both mid wave IR and long wave IR seed beams are first generated, and then amplified via one or more optical parametric chirped-pulse amplification stages. A compressor may be used to compress one or more of the output beams to achieve high peak power and controllable pulse duration in the output beams. The output beams may then be used to create atmospheric or material effects at km range.

Abstract: The system and method for enhancing and suppressing radio frequency (RF) emissions in a laser induced plasma system using a second laser. A first igniter laser is used at short pulse widths and a second heater laser is used at longer pulse widths. By varying the energy of the heater laser and/or the timing of the arrival of the heater laser with respect to the igniter laser suppression and/or enhancement of the radio frequency (RF) emission from the induced plasma system is possible.

Abstract: Techniques are provided for a multiwavelength laser source and a method of driving the multiwavelength laser source. The multiwavelength laser source includes: a plurality of seed lasers to generate a corresponding plurality of seed beams having a corresponding plurality of distinct seed wavelengths; a laser combiner to receive and combine the seed beams into a single first beam; an optical amplifier to amplify the first beam; and a single fixed nonlinear converter to convert and output the amplified first beam as a multiwavelength second beam including the seed wavelengths and one or more new wavelengths distinct from and generated from the seed wavelengths. In some embodiments, the nonlinear converter is an optical parametric oscillator (OPO) or an optical parametric generator (OPG). In some other embodiments, the nonlinear converter is a sum frequency generator (SFG), a difference frequency generator (DFG), or an optical parametric amplifier (OPA).

Abstract: The system and method for creating plasma flares in air by using an ultra-short pulse laser (USPL) that generates plasma filaments with a short lifetime (in nanoseconds), and by heating these plasma filaments with intense microwave (RF) radiation to induce robust air breakdown, resulting in long lifetime (up to milliseconds) plasma flares in the atmosphere.

Abstract: Techniques and architecture are disclosed for providing a laser system. In one specific example embodiment, the system includes a thulium-doped fiber laser coupled by silica glass fiber to a remote optical converter (ROC) including a Ho:YAG laser and, optionally, an optical parametric oscillator (OPO) utilizing in germanium phosphide (ZnGeP2; ZGP) or orientation-patterned gallium arsenide (OPGaAs). The fiber laser may emit a low-peak-power, continuous wave pump signal that pumps the Ho:YAG laser, which in turn emits a higher-peak-power, pulsed signal. When included, the OPO can be used to convert the resultant, pulsed signal to a longer wavelength (e.g., about 2-5 μm, or greater). In some cases, distributed architecture and reduced weight/bulk may be realized while eliminating the need to actively cool the ROC for operation, for example, over a broad temperature range (e.g., −55-125° C.). Also, methods of preparing high-peak-power, pulsed signals using such systems are disclosed.
