High-power femtosecond optical pulse compression by using spatial solitons.
We demonstrate a novel pulse-compression technique that uses the self-confinement of two-dimensional spatial solitons propagating in bulk nonlinear media to increase the spectral bandwidth followed by a grating pair for recompression. Output pulses of 19-fs duration with 0.6-,J energies are routinely obtained at a repetition rate of 8.6 kHz. Unlike other high-energy compression methods, soliton...
متن کاملHigh-temporal contrast using low-gain optical parametric amplification.
We demonstrate the use of low-gain optical parametric amplification (OPA) as a means of improving temporal contrast to a detection-limited level 10(-10). 250 microJ, 500 fs pulses of 1053 nm are frequency doubled and subsequently restored to the original wavelength by OPA with >10% efficiency.
متن کامل2. High Repetition Rate Pulse Source Using Pulse Compression through Optical Fiber
For next-generation optical networks, it is expected that transmission capacity will be increased by making high channel density and wide band WDM systems, and increasing data bitrate per wavelength channel. The high bitrate per channel system has great potential for cost reductions in comparison with wide broaden DWDM systems of the same transmission capacity, because of a fewer number of chan...
متن کاملPulse compression using a tapered microstructure optical fiber.
We calculate the pulse compression in a tapered microstructure optical fiber with four layers of holes. We show that the primary limitation on pulse compression is the loss due to mode leakage. As a fiber's diameter decreases due to the tapering, so does the air-hole diameter, and at a sufficiently small diameter the guided mode loss becomes unacceptably high. For the four-layer geometry we con...
متن کاملExtending the Radar Dynamic Range using Adaptive Pulse Compression
The matched filter in the radar receiver is only adapted to the transmitted signal version and its output will be wasted due to non-matching with the received signal from the environment. The sidelobes amplitude of the matched filter output in pulse compression radars are dependent on the transmitted coded waveforms that extended as much as the length of the code on both sides of the target loc...
