Characterization of non-planar ring oscillators at a wavelength of 1064 nm for high precision metrology
Abstract
Ultra-stable laser light is essential for high-precision interferometric measurements, in particular for the next generation of gravitational wave detectors, where high power lasers with unprecedented low power and frequency noise are demanded. Since the seed laser for high-power laser systems has a large influence on the overall noise characteristics, the use of the lowest noise seed laser is beneficial. This study compares a newly developed seed laser, based on a non-planar ring oscillator (NPRO) design, at a wavelength of 1064 nm with two commercial NPROs and shows that the new laser exhibits ten times lower power and frequency noise. This noise advantage is retained even after subsequent amplification to 40 W.
