In particular, VECSELs can be used to generate high power beams at yellow wavelength range [2], making it attractive for adaptive optics on earth-based telescopes. Their key advantages include ability to reach power levels of more than 10 W in fundamental transversal mode, low-noise single frequency operation, relatively broad wavelength tuning, and simpler and more compact architectures compared to alternative frequency converted solid-state laser systems used to generate visible radiation.We review progress in developing VECSEL technology with fundamental emission at 1180 nm and steps towards frequency doubled single-frequency systems at 590 nm range. The key enabling technology is the gain mirror, which has reached a maturity level suitable for generating more than 70 W at 1180 nm, with optical efficiencies in the range of 30{\%} [3].
