Premier said that the complaint is without merit and that it will defend itself aggressively.

In a development that could revolutionize dentistry and virtually eliminate the pain of having a cavity filled, the Food and Drug Administration on Wednesday approved the first laser system to treat tooth decay. The laser, made by Premier Laser Systems Inc. in Irvine, could usher in a new era in dentistry in which the often painful procedures involving the use of drills to remove tooth decay and prepare cavities for fillings will be replaced by relatively pain-free laser methods.

The stock of Trimedyne Inc. has leaped 72% in value in the past two days in an apparent response to a company's report that it has received federal regulatory approval to begin testing a second "cold" laser for opening blocked arteries in the heart. The company's stock climbed $1.25 to $5.375 in trading Thursday on the over-the-counter market. That followed a $1 gain on Wednesday. The stock spurt came after the Tustin-based maker of medical-laser products said that the U.S.

F or millions of Americans, the growth of the VCR in the '80s has turned living rooms into personal movie palaces. The popcorn may not be as tasty, the picture not as sharp and the sound not as forceful as in the real theater, but it's cheaper to rent a movie and the local video shop offers a far greater choice of pictures than even the neighborhood 10-plex. Laser discs now upgrade picture and sound to such a dramatic degree that they turn living rooms into concert halls.

After four days of trying, astronauts aboard the space shuttle Discovery received laser signals Sunday that were beamed up at them from Florida by the Defense Department. The lime-colored light signals, which contained navigation data, were sent from an Air Force facility in Palm Bay. "The green laser was clearly visible, visually and through the camera," said shuttle commander David Walker. "Whatever they've done to change the laser on the ground has fixed our problem."

Researchers have combined laser beams and specially coated glass to produce the first computer-type circuit that processes data with light rather than electronically, scientists say. The simple circuit is an important step in showing the feasibility of "optical computing," said Frank Tooley, a lecturer in the physics department of Heriot-Watt University in Edinburgh, Scotland. Tooley is co-author of a report on the circuit in today's issue of the British journal Nature.
