B. J. Orr
Brian J. Orr is an Australian scientist known for various experimental and theoretical contributions to molecular and optical physics, including laser spectroscopy and optical parametric oscillators. Biography Born in 1942, Orr grew up in Sydney and graduated with BSc (Hons I) and MSc from the University of Sydney. He received his PhD from the University of Bristol (UK) in 1968 and, after a postdoctoral period in Ottawa (Canada), returned to Sydney in 1969 to take up an academic position at the University of New South Wales. In 1988, he became Professor of Chemistry in the Faculty of Science at Macquarie University. Since 2003, Orr has been an Emeritus Professor, based in Macquarie University’s Department of Physics and Astronomy. His roles at Macquarie University have included service as Head of School/Department (1989–92/1999–2002), as Deputy Chair of the Academic Senate (1989–92), and as a member of the University Council (1999–2002).

Spectroscopy
Spectroscopy is the field of study that measures and interprets electromagnetic spectra. In narrower contexts, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of astronomy, chemistry, materials science, and physics, allowing the composition, physical structure and electronic structure of matter to be investigated at the atomic, molecular and macro scale, and over astronomical distances. Historically, spectroscopy originated as the study of the wavelength dependence of the absorption by gas phase matter of visible light dispersed by a prism. Current applications of spectroscopy include biomedical spectroscopy in the areas of tissue analysis and medical imaging. Matter waves and acoustic waves can also be considered forms of radiative energy, and recently gravitational waves have been associa ...

University Of Sydney Alumni
A university () is an educational institution, institution of tertiary education and research which awards academic degrees in several Discipline (academia), academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate education, undergraduate and postgraduate education, postgraduate programs. The first universities in Europe were established by Catholic Church, Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2 ...

Year Of Birth Missing (living People)
A year is a unit of time based on how long it takes the Earth to orbit the Sun. In scientific use, the tropical year (approximately 365 solar days, 5 hours, 48 minutes, 45 seconds) and the sidereal year (about 20 minutes longer) are more exact. The modern calendar year, as reckoned according to the Gregorian calendar, approximates the tropical year by using a system of leap years. The term 'year' is also used to indicate other periods of roughly similar duration, such as the lunar year (a roughly 354-day cycle of twelve of the Moon's phasessee lunar calendar), as well as periods loosely associated with the calendar or astronomical year, such as the seasonal year, the fiscal year, the academic year, etc. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by changes in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons a ...

Optical Parametric Oscillator
An optical parametric oscillator (OPO) is a parametric oscillator that oscillates at optical frequencies. It converts an input laser wave (called "pump") with frequency \omega_p into two output waves of lower frequency (\omega_s, \omega_i) by means of second-order nonlinear optical interaction. The sum of the output waves' frequencies is equal to the input wave frequency: \omega_s + \omega_i=\omega_p. For historical reasons, the two output waves are called "signal" and "idler", where the output wave with higher frequency is the "signal". A special case is the degenerate OPO, when the output frequency is one-half the pump frequency, \omega_s=\omega_i=\omega_p/2, which can result in half-harmonic generation when signal and idler have the same polarization. The first optical parametric oscillator was demonstrated by Joseph A. Giordmaine and Robert C. Miller in 1965, five years after the invention of the laser, at Bell Labs. Optical parametric oscillators are used as coherent light ...

Royal Australian Chemical Institute
The Royal Australian Chemical Institute (RACI) is both the qualifying body in Australia for professional chemists and a learned society promoting the science and practice of chemistry in all its branches. The RACI hosts conferences, seminars and workshops. It is the professional body for chemistry in Australia, with the ability to award the status of Chartered Chemist (CChem) to suitably qualified candidates. History The RACI was formed as the Australian Chemical Institute in Sydney in September 1917. The driving force was David Orme Masson, professor of chemistry at the University of Melbourne. It was incorporated under the Companies Act in New South Wales in 1923. It was given a royal charter in 1932, but it was not until a supplementary royal charter in 1953 that "Royal" was added to the title of the institute. It moved to Melbourne in 1934. It was incorporated in Victoria in 2000. Since 1993, the institute has had its office at 21 Vale Street, North Melbourne, VIC 3051, Aus ...
