Nanosecond Pulse Shaping with Fiber-Based Electro-Optical Modulators and a Double-Pass Tapered Amplifier
Charles E. Rogers, Phillip L. Gould
We describe a system for generating frequency-chirped and amplitude-shaped pulses on time scales from sub-nanosecond to ten nanoseconds. The system starts with cw diode-laser light…
Production of Ultracold Molecules with Chirped Nanosecond Pulses: Evidence for Coherent Effects
J. L. Carini, J. A. Pechkis, C. E. Rogers +3
We use frequency-chirped light on the nanosecond time scale to produce ultracold Rb molecules in the lowest triplet state via the process of photoassociation. Comparin…
Coherent control of ultracold 85Rb trap-loss collisions with nonlinearly frequency-chirped light
J. A. Pechkis, J. L. Carini, C. E. Rogers +3
We present results on coherent control of ultracold trap-loss collisions using 40 ns pulses of nonlinearly frequency-chirped light. The chirps, either positive or negative, sweep ~…
Creation of arbitrary spectra with an electro-optic modulator
C. E. Rogers, J. L. Carini, J. A. Pechkis +1
We use a waveguide-based electro-optic phase modulator, driven by a nanosecond-timescale arbitrary waveform generator, to produce an optical spectrum with an arbitrary pattern of s…
Characterization and Compensation of the Residual Chirp in a Mach-Zehnder-Type Electro-Optical Intensity Modulator
C. E. Rogers, J. L. Carini, J. A. Pechkis +1
We utilize various techniques to characterize the residual phase modulation of a fiber-based Mach-Zehnder electro-optical intensity modulator. A heterodyne technique is used to dir…
Generation of Arbitrary Frequency Chirps with a Fiber-Based Phase Modulator and Self-Injection-Locked Diode Laser
C. E. Rogers, M. J. Wright, J. L. Carini +2
We present a novel technique for producing pulses of laser light whose frequency is arbitrarily chirped. The output from a diode laser is sent through a fiber-optical delay line co…
