Thermal lensing due to the absorption of the laser beam in core optics of gravitational wave interferometers can represent a strong limitation to their operation and sensitivity. This effect has already been observed in the present detectors and will become more relevant in the future upgraded interferometers, due to the much higher circulating power. A thermal compensation system, based on a CO2 laser projector, has been installed in Virgo, allowing to increase the interferometer input power...[Show more]
