DEFINITION

Classification: 445/28

Flash lamp, X-ray tube or laser making:

(under subclass 23) Method for fabricating or manufacturing a device that, (1) produces bursts of light of short duration and high intensity such as are used for photography, or (2) produces a penetrating electromagnetic radiation known as roentgen rays such as by accelerating electrons to high velocity and suddenly stopping them by collision with a solid target or body, or (3) produces a narrow beam of coherent, powerful and nearly monochromatic electromagnetic radiation using the laser principle of light amplifications by stimulated emission of radiation, i.e., LASER.
