In the work presented is the theoretical description of optimal focusing of extended laser beam at long distances (over 1km). It is shown that in general case the optimal focusing condition does not ...

In this paper, we study the performance of unmanned aerial vehicle (UAV)-based free-space optical (FSO) systems over atmospheric turbulence channels considering the pointing misalignment and UAV ...

Optical Surfaces Ltd. has announced its reflective beam expanders are now available with the option to optimally operate in high vacuum environments, expanding or reducing high power laser beams.

Looking forward to a future where laser beams replace power lines, DAPRA's Persistent Optical Wireless Energy Relay (POWER) program has set new records for transmitting more power wirelessly over ...

Optical Surfaces Ltd. has announced its reflective beam expanders are now available with the option to optimally operate in high vacuum environments, expanding or reducing high power laser beams.

Accuracy Most laser levels are self-leveling, using an internal pendulum and magnet mechanism to indicate when the beam is completely level (and blinks to indicate it's not level yet).

Although the achievement marked the onset of ceramic-laser technology, the considerably low oscillation efficiency of the laser disappointed material and laser scientists.
