“…This light stimulates photon emission inside the slab that is being energised or 'pumped'by diode laser light delivered to the slab by the 72 optical fibres (top and bottom). and 100 W of pumping power, a near-diffraction limited 20 W laser output was produced (Mudge et al 2000). A scaled-up version is now being tested to produce a target output of 100 W using 520 W of pumping power.…”

An enormous effort is underway worldwide to attempt to detect gravitational waves. If successful, this will open a new frontier in astronomy. An essential portion of this effort is being carried out in Australia by the Australian Consortium for Interferometric Gravitational Astronomy (ACIGA), with research teams working at the Australia National University, University of Western Australia, and University of Adelaide involving scientists and students representing many more institutions and nations. ACIGA is developing ultrastable high-power continuous-wave lasers for the next generation interferometric gravity wave detectors; researching the problems associated with high optical power in resonant cavities; opening frontiers in advanced interferometry configurations, quantum optics, and signal extraction; and is the world's leader in high-performance vibration isolation and suspension design. ACIGA has also been active in theoretical research and modelling of potential astronomical gravitational wave sources, and in developing data analysis detection algorithms. ACIGA has opened a research facility north of Perth, Western Australia, which will be the culmination of these efforts. This paper briefly reviews ACIGA's research activities and the prospects for gravitational wave astronomy in the southern hemisphere.

“…Different continuous-wave, single-frequency lasers at a wavelength of 1064 nm were used in these experiments with output powers ranging from about 200 mW to 12 W. Many experiments use the laser pump power to control the output power of the system [9][10][11][12][13][14]. This is a good choice since pump power fluctuations often cause the laser output power fluctuations in the frequency band of interest.…”

“…In the recent decade several power stabilization experiments, among others [8][9][10][11][12][13][14][15][16][17], were performed specifically for GWDs. Most stabilizations use photodetectors, feedback control loops, and various actuators to reduce technical laser power noise in a frequency band from about 10 Hz to 10 kHz.…”

New concepts and results in laser power stabilization

In the recent decade the development of highpower, high-sensitivity photodetectors and low-noise sensing techniques lead to achievable relative power stabilities at the level of 10 −9 Hz −1/2 for frequencies between about 10 Hz and 10 kHz. A new power stabilization concept involving the novel optical ac coupling technique complements these high-sensitivity photodetectors. This technique improves the sensitivity of a photodetector by about one order of magnitude. Furthermore, it beats the quantum limit of traditional power stabilization concepts and opens a whole new range of attainable power stabilities that seemed to have been inaccessible due to technical limitations before. In this article we review various laser power stabilization experiments in the field of ground-based gravitational wave detectors, present the best results and discuss their limits.

“…NJECTION-LOCKING of a slave laser by a lower-power single-frequency stable master laser is an excellent method of producing a higher power single-frequency stable laser [1]- [9]. However, the slave laser can be injection-locked only if the frequencies of the master and slave lasers differ by less than the injection-locking range [10], [11].…”
