TL;DR: In this paper, the photonic flame effect (PFE) was observed in three-dimensional synthetic opals (synthetic opals) placed on a Cu plate at the temperature of liquid nitrogen (77 K).
Abstract: We observed a new effect which we called the photonic flame effect (PFE). Several three-dimensional photonic crystals (synthetic opals) were posed on a Cu plate at the temperature of liquid nitrogen (77 K). The typical distance between the crystals was 1–5 cm. A long-continued optical luminescence was excited in one of the crystals by the ruby laser pulse. A visible luminescence appeared in the other crystals (not illuminated by the laser pulse), with a time delay with respect to the luminescence in the first crystal (illuminated by the laser pulse) being observed. We examined synthetic opal crystals and those filled with nonlinear liquids.

TL;DR: In this article, a tunable dye laser system pumped by a ruby laser was used to generate IR radiation from 4.1 to 5.2 μm. But the IR radiation was obtained as output in the spectral region.

TL;DR: In this article, the properties of the annealed films were studied as a function of laser energy by means of electron microscopy, photoluminescence and infra-red absorption.
Abstract: Glow discharge amorphous silicon layers have been annealed using a Q-switched ruby laser. The properties of the annealed films were studied as a function of laser energy by means of electron microscopy, photoluminescence and infra-red absorption. The changes in structure, hydrogen content, band-gap and density of states in the annealed layers are discussed. It is found that there are considerable similarities between the amorphous and the annealed material.

TL;DR: The successful long-term elimination of common blue nevus is reported on the nasal skin of two patients whose lesions were treated with the laser emission of 694 nm energy from the Q-switched ruby laser.
Abstract: The common blue nevus is a benign, localized collection of dermal melanocytes. To date, removal required excisional surgery to eliminate pigment that usually extends into the reticular dermis. We report the successful long-term elimination of common blue nevi on the nasal skin of two patients whose lesions were treated with the laser emission of 694 nm energy from the Q-switched ruby laser.

TL;DR: In this article, a 10nsec pulsed ruby laser was used to prepare atomically clean silicon surfaces in UHV and showed that the phase transition of silicon does not depend on the ambient conditions or on the native surface oxide layer of silicon.
Abstract: A 10‐nsec pulsed ruby laser was used to prepare atomically clean silicon surfaces in UHV. With picosecond Nd:YAG laser pulses at 532 amd 266 nm, the amorphous patterns formed on the atomically clean silicon surfaces in UHV were compared with those formed in air and other ambient conditions. Results show that the picosecond laser‐induced phase transition of silicon does not depend on the ambient conditions or on the native surface oxide layer of silicon.
