Laser Worlds Now Underway:
Nuevo Vallarta, Mexico (May 12, 2016) – The Laser Standard Men’s World Championship got underway today for 114 competitors representing 44 different countries. The first four days are qualifying, with the sailors divided into two fleets before the top group advances to vie for the title on May 16-18. After two qualifying races, reigning world champion Nick Thompson (GBR) and Tonci Stipanovic (CRO) lead their respective fleets. Full report.

Tenth Anniversary of Lightning Boat Grant Program:
The International Lightning Class is celebrating the 10th Anniversary of their Boat Grant Program, which to date has introduced 29 teams and 90+ participants to the Lightning Class. The 2016 recipients of the ILCA Boat Grant Program are Gordon Wolcott of Virginia Beach, VA/University of VA Alumni and Andreas Adam of Annapolis, MD/SUNY Maritime. The ILCA provides to selected applicants a competitive boat, insurance, mentoring, and substantial regatta expense reimbursement. Full report.

It has been 50 years since laser was first invented by Theodore Maiman at Hughes Research Laboratories in the year 1960. Since then it has found numerous applications. After 50 years laser has now met its match, the so-called anti-laser, which has been built at the Yale University. Named coherent perfect absorber (CPA), physicist A. Douglas Stone and a team of his colleague Hui Cao worked upon the initial theory published by Douglas Stone to build this device.

Absorption of incoming laser light by the anti-laser, which theoretically should be 99.99 percent, is currently 99.4 percent. This is due to experimental limitation, but the scientist said that the CPA that they have built is just a “proof of concept.” Stone said, “I’m confident we will start to approach the theoretical limit as we build more sophisticated CPAs.” Commenting on size of the CPA, Stone said that using computer simulation, they could reduce the size from 6 centimeters to 6 microns across. The results of the study were published in the Feb. 18 issue of the journal ‘Science.’
Conception of idea
“It went from being a useful thought experiment to having me wondering whether you could really do that,” Stone said. The idea of building an anti-laser came up when he was explaining the complicated physics behind lasers to a visiting professor. While suggesting his colleagues about building a device that could reverse the behavior of laser light, he contemplated whether such a device could actually be built. “After some research, we found that several physicists had hinted at the concept in books and scientific papers, but no one had ever developed the idea.”
Application of anti-laser
It is Stone’s belief that the CPA could be used as optic switches, detectors and as other components in the next generation of computers called optic computers, which would run on light in addition to electrons. According to him, another application of CPA could be in radiology where its principle could be used to focus electromagnetic radiation to a small region normally located within opaque human tissue for either therapeutic or imaging purpose.
