New Q-switch compounds for infrared lasers

Abstract

<tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Q</tex> switching of an Nd-glass laser by a solution of the transition metal complex bis-(4-dimethylaminodithiobenzil)-nickel is reported. The special advantage of the new <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Q</tex> -switch dye lies in its extreme photochemical stability.
