Laser frequency can be converted very efficiently nowadays using electrically field poled ferroelectric crystals, such as LiNbO3 or KTiOPO4. Unfortunately, these crystals are readily available only with relatively small aperture – up to 1 mm in the critical Z axis of the crystal – thereby severely l.....

As any lover of live sports events knows, user control of a video camera’s viewpoint can be a highly prized feature. Unfortunately, it is not feasible to allow each viewer to actively control his own robotic video camera from home. Some partial solutions to this problem include the simultaneous stre.....

Background:Stirling cycle-based cryocoolers employ mechanical compressors activated by inductive electrical motors producing an oscillating pressure in a gas. The main disadvantage of these conventional compressors is their limited lifetime, caused by mechanical friction and wear. Wear products degr.....
