All precision communication and measurement systems (i.e. radar and navigation) rely on high quality oscillator technology. Any improvement in oscillator performance has a direct impact on the performance of the system and hence is of potential economic benefit. This project will realise the most stable frequencies ever produced in the underused Extremely High Frequency band, which is also important for space communications and navigation technology. System enhancement will include, better angular resolution, higher bandwidths, faster transmission rates and narrower beam widths without the susceptibility of absorption apparent from the optical domain.Read moreRead less
A Laser Guide Star using a High Power, Synchronously Pumped Optical Parametric Oscillators. We will develop a novel high power source of 589nm coherent (laser) light to be used to create a laser guide star by exciting sodium atoms in the earth's upper atmosphere (the mesosphere). This is needed to determine the distortion caused by the atmosphere on an optical beam propagating through it and generate the information needed to correct those distortions using an adaptive optics telescope.
