We report the detection of pulsed gamma-rays from the young, spin-powered radio pulsar PSR J2021+3651 using data acquired with the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope (formerly GLAST). The light curve consists of two narrow peaks of similar amplitude separated by 0.468 ± 0.002 in phase. The first peak lags the maximum of the 2… (More)
Following its launch in June 2008, the Fermi Gamma-ray Space Telescope (Fermi) began a sky survey in August. The Large Area Telescope (LAT) on Fermi in 3 months produced a deeper and better-resolved map of the γ-ray sky than any previous space mission. We present here initial results for energies above 100 MeV for the 205 most significant (statistical… (More)
We generate ultra-broadband 6.5 μm pulses with 2.3 cycle transform limit and 85 pJ energy at 100 MHz from a phase-coherent, two-color, two-arm Er:Tm:Ho all-fiber MOPA system in CdSiP<sub>2</sub>.
The Quantum Nanostructures and Nanofabrication Group focuses research on questions surrounding the application and fabrication of devices whose operation is based on the foundations of quantum mechanics. Because of the macroscopic extent of the superconductive wavefunction, superconductive devices are the most readily engineered examples of these types of… (More)
For an epitaxial Pr(0.48)Ca(0.52)MnO(3) film on NdGaO(3), we use transmission electron microscopy to observe a 'charge-ordered' superlattice along the in-plane direction a. The same film shows no electrical signatures of charge order. The in-plane electrical anisotropy ρ(a)/ρ(c) = 28 is constant, and there is no evidence of sliding charge density waves up… (More)
We demonstrate the first picosecond cryogenic Ho:YLF CPA system with Er:Tm:Ho fiber seeder. The system delivers energy-scalable 13-mJ pulses with 10-ps duration at 100 Hz repetition rate.
We generate octave-spanning pulses centered at 10 μm with 100-mW-scale average powers and 100-MHz repetition rate via intrapulse difference-frequency mixing driven in LiGaS<sub>2</sub> by a nonlinearly compressed Kerr-lens mode-locked Yb:YAG thin-disk oscillator.
