Abstract
Diode-pumped miniature ring lasers1 are well known as reliable sources of stable radiation for high resolution spectroscopy and interferometer based metrology. Especially extremely high resolution are required for the detection of gravitational waves using Michelson type interferometers. For these systems a light source with high continuous wave output power in single-frequency operation, excellent frequency stability and extremely low amplitude noise as close to the quantum noise limit as possible is essential. Based on the miniature ring laser a light source has been developed that has the potential to meet these requirements. This contribution reports on the substantial progress in the properties of this light source.
