A fast semi-analytical method for propagating leaky Lamb wavefields
(Chapter, 2021)A fast method is presented for calculating the wavefields from initialized leaky Lamb waves on plates immersed in sufficiently light fluids. The method works by precomputing the dispersion relation and attenuation, and ... -
Femtosecond laser writing of the depressed cladding buried channel waveguides in ZnS crystal
(Chapter, 2018)We report the first direct laser-writing of buried channel waveguides in ZnS. A depressed cladding waveguide with propagation loss of 0.62 dB/cm at 1030 nm allowed to obtain spectral broadening under femtosecond-pumping ... -
Femtosecond Operation and Random Quasi-Phase-Matched Self-Doubling of Ceramic Cr:ZnSe Laser

Femtosecond operation and self‐doubling of Cr:ZnS laser
(Chapter, 2011)Prismless dispersion‐controlled Cr:ZnS laser generates first femtosecond (110 fs) pulses at 180 MHz repetition rate around 2400 nm with average power 200 mW. Copropagating second‐harmonic pulse at 1200 nm is simultaneously ... -
Field dependent conductivity of n-pentane
(Chapter, 2017)A sensitive differential charge measurement technique was used to measure the conduction current from a sharp needle in a needle plane geometry in n-pentane. The current was measured at voltages up to the threshold for ... -
Gigahertz Femtosecond Cr:ZnS Laser
