Researchers Develop Laser Prototype for the Space-Based Gravitational Wave Observatory

An international group of researchers has developed laser prototype at the heart of the first space-based gravitational wave observatory, known as the Laser Interferometer Space Antenna (LISA) mission. The new laser nearly meets the stringent requirements outlined for LISA’s instrumentation, representing an important step toward bringing the ambitious observatory program to fruition. Steve Lecomte of the Swiss research firm CSEM, will present details of the prototype’s performance at The Optical Society’s (OSA) 2019 Laser Congress, held 29 September to 3 October in Vienna, Austria.
