TL;DR: The time-resolved optical transmission and reflectivity of $n$-type crystalline silicon has been observed during and after pulsed-laser irradiation in this paper.
Abstract: The time-resolved optical transmission and reflectivity of $n$-type crystalline silicon has been observed during and after pulsed-laser irradiation. The transmission goes to zero, and remains at zero, during the period of enhanced reflectivity, contradicting reports of earlier experiments. Our measurements are in quantitative agreement with results of thermal melting model calculations and with known optical properties of molten silicon.

TL;DR: The principle that laser frequencies which are appropriately matched to the absorption characteristics of target molecules can selectively inhibit specific molecular components in intact cells, if a controlled energy density range is used is illustrated.
Abstract: A frequency of 5300 A, derived from a frequency-doubled Q-switched neodymium laser was observed to produce progressive injury and death of cells from a culture of newborn rat cerebellum A subsequent observation that the green laser frequency (but not 6943 A of the same intensity from a Q-switched ruby laser) could reduce the rate of oxygen consumption of rat brain cell suspensions suggested that the cytochromes may serve as chromophores This hypothesis was confirmed by a demonstration that cytochromes c+c1 failed to act as hydrogen acceptors following 10 impacts of 1 Mw/cm2 each of the green laser frequency and cytochromes a+a3 showed a similar response when a brain cell suspension was irradiated (200 kw) with frequencies of 6096 and 6013 A These data illustrate the principle that laser frequencies which are appropriately matched to the absorption characteristics of target molecules can selectively inhibit specific molecular components in intact cells, if a controlled energy density range is used

TL;DR: In this article, an optical parametric oscillator was achieved in LiNbO3 in the range 1 to 1.08 μ with a peak parametric power of 38 × 103 W. The oscillator which was tuned both by rotation of the crystal in an external optical cavity and by the electro-optic effect was pumped at 6943 A by a ruby laser of 3 × 106 W peak power.
Abstract: Optical parametric oscillation has been achieved in LiNbO3 in the range 1 to 1.08 μ with a peak parametric power of 38 × 103 W. The oscillator which was tuned both by rotation of the crystal in an external optical cavity and by the electro‐optic effect was pumped at 6943 A by a ruby laser of 3 × 106 W peak power. The observed electro‐optic tuning agreed with that calculated from measured values of the electro‐optic coefficients.

TL;DR: In this article, a data-treatment procedure was proposed for more accurate determination of electron temperatures and electron concentrations in analytical plasmas. But the method is not suitable for the measurement of electron energy.

TL;DR: Optical parametric oscillation has been achieved in LiIO3 pumped by a pulsed ruby laser, with tunable output to 4μ as discussed by the authors, and the operation of the singly resonant oscillator is described and threshold measurements are compared with theory.
