A New European Amateur Laser Communications Distance Record
The UK and European distance record for laser communications has been
beaten - by the same team that set the previous record. On Wednesday the 8th
of October, David, G0MRF, and Allan, G8LSD, completed a contact on a
wavelength of 670 nanometres over a distance of 76.1 kilometres. G0MRF was
at Butser Hill in Hampshire, while G8LSD went to Ashdown Forest in East
Sussex for the contact. The previous record, 49 kilometres, was set by David
and Allan on the 5th of April this year. The equipment used was the same:
G8LSD used a 3 milliwatt laser diode to a beam expander with a Burr-Brown
detector as a replacement eyepiece for a Russian 4.5 inch reflector
telescope as a receiver. G0MRF used a 10 milliwatt laser diode without beam
expander and, on receive, a wider-bandwidth OPT210 detector. The contact was
made more difficult due to the poor weather conditions prevailing on the
night. Further details are on Allan's Laser Communications website, which is
linked from the RSGB site at www.rsgb.org
