Journal ArticleDOI
Coupled‐Wave Theory of Distributed Feedback Lasers
H. Kogelnik,Charles V. Shank +1 more
TL;DR: In this article, an analysis of laser action in a periodic structure is presented, where the resonant frequencies and threshold criteria for the modes of oscillation have been determined for both index and gain periodicities.
Journal ArticleDOI
Generation of optical pulses shorter than 0.1 psec by colliding pulse mode locking
TL;DR: In this article, a novel passive mode-locking technique was proposed in which two synchronized counterpropagating pulses interact in a thin, saturable absorber to produce a short pulse.
Journal ArticleDOI
Direct observation of the femtosecond excited-state cis-trans isomerization in bacteriorhodopsin
TL;DR: In this article, a 60-femtosecond pump pulse at 618 nanometers was used to study the primary photoprocesses in the light-driven transmembrane proton pump bacteriorhodopsin.
Journal ArticleDOI
Astigmatically compensated cavities for CW dye lasers
TL;DR: In this article, a method to compensate the astigmatic distortions introduced by both the internal mirror and the cell is described, which allows the formation of a tight intracavity focus as required in applications such as CW dye lasers.
Journal ArticleDOI
Femtosecond-Time-Resolved Surface Structural Dynamics of Optically Excited Silicon
TL;DR: In this article, the dynamics of the structural changes that take place on a silicon surface following excitation with an intense optical pulse are observed with 90-fs time resolution, and the threefold rotational symmetry of the silicon surface becomes rotationally isotropic within a picosecond after excitation consistent with a transition from the crystalline to the liquid molten state.
