41. Quanta-Ray commercialized a high-energy pulsed laser invented in the Byer lab which is still widely used in scientific research. 42. Their work includes both experimental and theoretical studies using low energy pulsed lasers both without and with an opaque overlay. 43. Pulsed laser deposition is a variant of the sputtering deposition technique in which a laser beam is used for sputtering.44. Role of the sputtered and resputtered ions and the background gas is fully investigated during the pulsed laser deposition process. 45. Ruby pulse laser , built in collaboration with Professor Jesper Munch of the School of Chemistry and Physics at Adelaide University. 46. In this picture, a high-intensity pulsed laser shoots a rotating white disk of Al 2 O 3 ( alumina ). 47. Material is directly removed from a solid or liquid surface at high velocities by laser ablation by a pulsed laser . 48. The table below summarizes the various medical conditions caused by lasers at different wavelengths, not including injuries due to pulsed lasers . 49. Toshiba said last month that it has used gallium-nitride compounds to create a blue-purple semiconductor laser that emits a pulsed laser beam. 50. The prototype of quantum cryptography developed by IBM uses a fast pulse laser that is filtered to produce one photon per pulse.
