Ultrashort laser pulse characterization using modified spectrum auto-interferometric correlation (MOSAIC).
Sensitive, real-time chirp and spectral phase diagnostics along with full field reconstruction of femtosecond laser pulses are performed using a single rapid-scan interferometric autocorrelator. Through the use of phase retrieval error maps, ambiguities in pulse retrievals based on the pulse spectrum and various forms of MOSAIC traces are discussed. We show second-order autocorrelations can int...
متن کاملExperimental determination of temporal asymmetry of ultrashort laser pulses using unbalanced modified spectrum auto-interferometric correlation technique
We report experimental implementation of an unbalanced modified spectrum auto-interferometric correlation (UMOSAIC) technique for visual detection and estimation of the laser pulse temporal asymmetry without direction-oftime ambiguity. This is based on modification of the spectral contents of second order unbalanced interferometric autocorrelation (U-IAC) signals. We use a commercial AlGaAs lig...
متن کاملComplementary ultrashort laser pulse characterization using MOSAIC and SHG FROG.
A new (to our knowledge) method for generating the modified spectrum autointerferometric correlation (MOSAIC) trace from the second-harmonic generation frequency-resolved optical gating (SHG FROG) dataset is shown. Examples are presented illustrating enhanced visual sensitivity, applicability, and complementary qualitative pulse characterization using SHG FROG.
متن کاملModified spectrum autointerferometric correlation (MOSAIC) for single-shot pulse characterization.
A method for generation of the modified spectrum autointerferometric correlation that allows single-shot pulse characterization is demonstrated. A sensitive graphical representation of the ultrashort pulse phase quality is introduced that delineates the difference between the presence of temporal and spectral phase distortions. Using these schemes, full-field reconstruction of ultrashort laser ...
متن کاملHigh-sensitivity ultrashort mid-infrared pulse characterization by modified interferometric field autocorrelation.
We report on spectral phase retrieval of 43 MHz, ∼100 fs, 3.3 μm pulses at energies down to 8.9 pJ by a modified interferometric field autocorrelation method. The simple setup consists of a Michelson interferometer, a 266 μm thick AgGaSe2 crystal, and a homemade spectrometer with an InGaAs point detector, which is readily applicable to measuring a 20 fs (1.8 cycles) pulse at 3.3 μm....
