Wave collapse and optical-pulse compression
Physical Review A, 1993The past several decades of development of nonlinear optics clearly demonstrated an important role playing by universal nonlinear models. Simply formulated, but, at the same time, rich in content, the models such as the nonlinear Schrödinger equation, the sine-Gordon equation, the system describing three-wave resonant interaction, and others occur in a

Four-wave mixing with femtosecond pulses
Physica Scripta, 2009The recent development of noncollinear optical parametric amplifiers (NOPAs) has equipped many laboratories with widely tunable, spectrally broad ultrashort laser pulses with a duration of 15-30 fs. The present work deals with sub-20 fs pulsed degenerate four wave mixing (DFWM) on high-frequency vibrational levels in all-trans-beta-carotene.

Pulse Wave Velocity and Pulse Wave Analysis in Experimental Animals
2012Until a few years ago, pulse wave velocity in experimental animals (mice, rats, rabbits, etc.) could only be measured by invasive methods. The carotid or femoral artery was surgically isolated and catheterized to assess intra-arterial pressure. The carotid and femoral signals were measured simultaneously, and the pulse wave transit time was then ...
