21. A Green Laser Pointer Hazard
Series: Technical Note (NIST TN)
Report Number: 1668
Published: 8/2/2010
Authors: Jemellie Galang, Alessandro Restelli, Edward W Hagley, Charles W Clark
Abstract: An inexpensive green laser pointer was found to emit 20 mW of infrared radiation during normal use. This is potentially a serious hazard that would not be noticed by most users of such pointers. We find that the problem derives from an unsafe desig ...

22. Matter-wave self-imaging in non-Raman-Nath regime pulsed standing optical wave
Published: 12/18/2008
Authors: Ke Li, Lu Deng, Edward W Hagley, M.S. Zhan, M Payne
Abstract: We demonstrate matter-wave self-imaging in a stationary light field in the non-Raman-Nath limit. We show that in a non-instantaneous pulsed standing wave grating significant contributions due to the non-negligible atomic center of mass motion and ins ...

23. A Fast-Responding Nonlinear Phase Shifter Using an Active Raman Gain Core
Published: 4/22/2008
Authors: Lu Deng, Edward W Hagley, Kaijun Jiang, M Payne
Abstract: Using a lifetime broadened N-scheme with an active-Raman-gain (ARG) Lambda core, we show that large nonlinear phase shift can be induced without signal wave attenuation. The new scheme is not based on the ultra-slow-wave technique and it does not ex ...

24. Formation and propagation of matched and coupled ultraslow optical soliton pairs in a four-level double-Lambda system
Published: 11/17/2005
Authors: Lu Deng, M G Payne, G X Huang, Edward W Hagley
Abstract: We investigate the simultaneous formation and stable propagation of ultraslow optical soliton pairs in a lifetime broadened four-state atomic system under double- excitation with large one- and two- photon detunings. We show that detrimental pr ...

25. Propagation Dynamics of a Temporally, Amplitude- and Group-Velocity-Matched Two-Mode Ultraslow Wave in a Three-Level Lamda System
Published: 12/1/2004
Authors: Lu Deng, M Payne, Edward W Hagley
Abstract: We investigate the propagation dynamics of a two-mode probe field traveling with ultra-slow group velocities. We show that a strong cross-beam coupling occurs between the two modes of the probe wave. In the adiabatic limit and under appropriate con ...

26. Quantum Key Distribution With 1.25 Gbps Clock Synchronization
Published: 5/1/2004
Authors: Joshua C Bienfang, Alex J Gross, Alan Mink, Barry J. Hershman, Anastase Nakassis, Xiao Tang, David H Su, Charles W Clark, Carl J Williams, Edward W Hagley, J Wen, R Lu

27. Efficient multi-wave mixing in ultra slow propagation regime and the role of multi-photon quantum destructive interference,
Published: 1/18/2004
Authors: Y Wu, M G Payne, Edward W Hagley, Lu Deng
Abstract: We analyze a lifetime-broadened four-state four-wave-mixing (FWM) scheme in the ultraslow propagation regime and show that the generated FWM field can acquire the same group velocity and pulse shape as those of an ultraslow pump field. We show ...
