(Top) Fabrication of antireflective microlens arrays. For details see Pacholski et al., pp. 8-14. (Bottom) Advances in single-pass second-harmonic generation combined with
progress in fiber laser technology can now provide continuous-wave green sources at
unprecedented powers, with competitive performace over traditional solid-state pump
lasers, enabling the development of fiber-laser-pumped Ti:sapphire lasers. For details
see Kumar et al., pp 15-20.
