Spectral Broadening Effects on Pulsed-Source Digital Holography Open
Using a pulsed configuration, a digital-holographic system is setup in the off-axis image plane recording geometry, and spectral broadening via pseudo-random bit sequence is used to degrade the temporal coherence of the master-oscillator l…

Digital-holography efficiency measurements using a heterodyne-pulsed configuration Open
A digital-holography (DH) system is created in a heterodyne-pulsed configuration, meaning that the reference and signal pulses are nondeterministically correlated in time. Using the off-axis image plane recording geometry, two performance …

Impacts of Laboratory Vibrations and Laser Flicker Noise on Digital Holography Open
In this paper, we experimentally demonstrate the impacts of laboratory vibrations and laser flicker noise on digital holography (DH). Specifically, we measure both the vibration efficiency and the coherence efficiency of our DH system at v…

Digital holography experiments with degraded temporal coherence Open
To simulate the effects of multiple-longitudinal modes and rapid fluctuations in center frequency, we use sinusoidal phase modulation and linewidth broadening, respectively. These effects allow us to degrade the temporal coherence of our m…

Plasma spectroscopy of titanium monoxide for characterization of laser ablation Open
Ablation of titanium wafers in air is accomplished with 60 µs pulsed, 2.94 µm laser radiation. Titanium monoxide spectra are measured in the wavelength range of 500 nm to 750 nm, and molecular signatures include bands of the C 3 Δ → X 3 Δ …
