Methods and devices for inhibiting hair growth and related skin treatments
Nikolai J. Tankovich,Kurt A. Dasse,David H. Fine,Paul W. Fairchild,Zhong-Quan Zhao,Michael Lefebvre,John Lee,Jonathan L. Rolfe,Susan Murrell,Allen M. Ii Hunter,Amanda J. Reynolds +10 more
TL;DR: The hair removal methods include controlling the proportions of photomechanical and photothermal damage by selection of laser parameters, chromophore particle size and/or pulse duration, with optional dynamic skin cooling.

Interaction length for optical phase conjugation by stimulated Brillouin scattering: an experimental investigation.
TL;DR: The parameters which govern the effective interaction length at threshold for phase conjugation due to stimulated Brillouin scattering are investigated and the length is found to be the shorter of the following parameters: the cell length, 3 times the coherence length or 5 times the Rayleigh range of the input laser radiation.

TL;DR: A cooling method and apparatus for use in combination with a laser for long-term hair removal and skin peeling is described in this article, where the skin surface is cooled so that skin tissue is maintained at temperatures below that which could cause tissue damage.

Living with adaptive secondary mirrors 365/7/24
Julian C. Christou,Guido Brusa,Juan Carlos Guerra,Michael Lefebvre,Douglas L. Miller,Gustavo Rahmer,R. Sosa,Michael Wagner +7 more
TL;DR: The Large Binocular Telescope (LBTO) has two adaptive secondary mirrors which are used for regular observing in both seeing-limited and diffraction-limited modes unlike the adaptive secondaries at the MMT and Magellan telescopes which are swapped in for diffractionlimited observing only as discussed by the authors.
