Laser Laser A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light "coherently". Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial
Laser 3000 using a shorter-footed mainsail with two full-width battens giving a larger roach. A mast with conventional spreaders replaced the now-unusual diamond arrangement of the Laser 2. The 3000 offers fast, exciting yet easy sailing, particularly for lighter sailors - couples, parent-child and teenage combinations are common at 3000 events. A modest rig size and forgiving nature means that if other classes are sailing on a windy day, any reasonably competently crewed 3000 will be able to join them and enjoy a sparkling sail. Originally built by Laser, boats tagged 'V3000' currently built to the design by VanderCraft are constructed from
