The performance of large ground-based optical telescopes is limited due to wavefront distortions induced by atmospheric turbulence. Adaptive optics systems using natural guide stars with sufficient brightness provide a practical way for correcting th

Large telescopes equipped with adaptive optics require 20-25W CW 589-nm sources with emission linewidths of ~5 MHz. These Guide Star (GS) lasers should also be highly reliable and simple to operate and maintain for many years at the top of a mountain

The rationale and design of a a 589-nm Laser Guide Star System, based on amplification of narrow-band diode laser seeds using ESO's patented Raman Fiber approach in the near infrared and subsequent resonant frequency doubling, developed and realized

In this paper we present the rationale and design of a compact, transportable, modular Laser Guide Star Unit, comprising a 589nm laser mounted on a 300mm launch telescope, to be used in future experiments probing the mesospheric sodium properties and

The quest of the astronomical instrumentation community for high-power, narrow-band CW laser guide stars (LGS) has been a challenge to the laser community for more than two decades now. Only recently, a new generation of rugged laser system developme

Dissociation energies for monomer evaporation from small (n ≤ 4) neutral and ionized molecular clusters are experimentally determined from the measured ionization potentials and the appearance potentials of the respective metastable decay channels
