Noninvasive identification of carbon-based black pigments with pump-probe microscopy
Heidi V. Kastenholz, Michael I. Topper, Warren S. Warren +2
Carbon-based black pigments, a widely used class of pigments, are difficult to differentiate with the noninvasive techniques currently used in cultural heritage science. We utilize…
Non-destructive Three-dimensional Imaging of Artificially Degraded CdS Paints by Pump-probe Microscopy
Yue Zhou, David Grass, Warren S. Warren +1
Cadmium sulfide (CdS) pigments have degraded in several well-known paintings, but the mechanisms of degradation have yet to be fully understood. Traditional non-destructive analysi…
Contrast mechanisms in pump-probe microscopy of melanin
David Grass, Georgia M. Beasley, Martin C. Fischer +3
Pump-probe microscopy of melanin in tumors has been proposed to improve diagnosis of malignant melanoma, based on the hypothesis that aggressive cancers disaggregate melanin struct…
Beyond intensity modulation: new approaches to pump-probe microscopy
Jun Jiang, David Grass, Yue Zhou +2
Pump-probe microscopy is an emerging nonlinear imaging technique based on high repetition rate lasers and fast intensity modulation. Here we present new methods for pump-probe micr…
Crossed-beam pump-probe microscopy
Jun Jiang, Warren S. Warren, Martin C. Fischer
We present a new imaging method for pump-probe microscopy that explores non-collinear excitation. This method (crossed-beam pump-probe microscopy, or CBPM) can significantly improv…
Controllable ultra-broadband slow light in a warm Rubidium vapor
Rui Zhang, Joel A. Greenberg, Martin C. Fischer +1
We study ultra-broadband slow light in a warm Rubidium vapor cell. By working between the D1 and D2 transitions, we find a several-nm window centered at 788.4 nm in which the group…
Observation of the Quantum Zeno and Anti-Zeno effects in an unstable system
M. C. Fischer, B. Gutierrez-Medina, M. G. Raizen
We report the first observation of the Quantum Zeno and Anti-Zeno effects in an unstable system. Cold sodium atoms are trapped in a far-detuned standing wave of light that is accel…
