METHOD FOR LASER MANUFACTURE, METHOD AND SYSTEM FOR ITS CONTROL Russian patent published in 2004 - IPC

FIELD: laser engineering; manufacture of photo-dissociative laser for shaping electromagnetic radiation pulses.

SUBSTANCE: laser manufacture includes manufacture of hollow cylinder with gas-tight inner surface and flanges with output windows; fixation of electromagnetic pulse initiators in cylinder interior; coupling of flanges with cylinder and installation of output windows; and admission of gas medium in working chamber. Working chamber cylinder is manufactured from plastic tubular billet; then rectangular plate is made of thin-sheet metal-plated material whose length exceeds length of tube and width is greater than tube bore circumference length; end zones of opposing surfaced of plate are run over with solder along its large sides, and fixing mechanisms of electromagnetic pulse initiators are installed on plate; the latter is folded along its larger side to form pipe with outer diameter smaller than inner diameter of tube, plate areas covered with solder being disposed on surfaces of overlapping areas of pipe facing each other; plate is secured in position in folded state and inserted into inner space of tube till its ends protrude from both end surfaces of tube; plate is released from fixation in folded state, pressed to inner surface of tube, plate areas run over with solder are subjected to heat treatment at temperature higher than melting point of solder; upon heat treatment plate ends protruding from end surfaces of tube are removed to obtain cylinder with gas-tight inner surface. Laser control method includes generation of control signal in the form of divergent electromagnetic radiation beam , conversion of this beam into annular-section beam followed by its supply along laser working chamber to triggering device of electromagnetic radiation pulse initiators. Lasing system has laser incorporating elongated working chamber with output windows at its ends; electromagnetic pulse initiators incorporating their triggering devices and disposed in opposition along working chamber; re-reflector mounted against one of working chamber windows; infrared radiation source, and mirror element with bore enclosing re-reflector tilted to optical axis of system. Triggering devices are made in the form of remote-control receivers whose inputs are optically coupled through mirror element with infrared radiation source.

EFFECT: greatly reduced mass and cost of laser.
