A laser-pushed lightsail is a thin reflective sail similar to a solar sail, in which the sail is being pushed by a laser, rather than the sun.The advantage of lightsail propulsion is that the vehicle does not carry either the energy source or the reaction mass for propulsion, and hence the limitations of the Tsiolkovsky rocket equation to achieving high velocities are avoided.
Masers could also be used to power a painted solar sail, a conventional sail coated with a layer of chemicals designed to evaporate when struck by microwave radiation. [39] The momentum generated by this evaporation could significantly increase the thrust generated by solar sails, as a form of lightweight ablative laser propulsion .
The Laser 3000 is a racing sailing dinghy crewed by two persons with a trapeze for the crew. Launched in 1996, the 3000 was developed from the Laser 2 , using the original Frank Bethwaite -designed planing hull combined with a brand new self-draining deck by Derek Clark.
A smaller sail plan for the Laser, the Laser 4.7 or ILCA 4, was developed about a decade after the Laser Radial. The sail area was reduced by 35% from the Standard (from 7 to 4.7 square metres (75 to 51 sq ft)) with a shorter, pre-bent bottom mast section, allowing even lighter sailors to sail it. The same formula as the Radial is kept.
The Laser 4.7 or ILCA 4 is a one-design dinghy class in the Laser series and is a one-design class of sailboat. All Lasers are built to the same specifications. The Laser is 4.06 m (13 ft 10 in) long, with a waterline length of 3.81 m (12 ft 6 in). The hull weight is 59 kg (130 lb).

The US-Israeli Tactical High Energy Laser (THEL) was used to shoot down rockets and artillery shells before being canceled in 2005 as a result of "its bulkiness, high costs and poor anticipated results on the battlefield". [1] A laser weapon [2] is a type of directed-energy weapon that uses lasers to inflict damage. Whether they will be ...
