Abstract

<abstract abstract-type="graphical" xml:lang="en" id="lpor201400031-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The interplay between vertical‐cavity and random lasing emission properties of a blue‐emitting molecular crystal is investigated. The emission spectra of the 1, 1, 4, 4‐tetraphenyl‐1, 3‐butadiene samples show narrow peaks for excitation threshold &gt;500 <italic>μ</italic>J cm⁻², attributed to both the built‐in vertical Fabry‐Pérot cavity and random lasing. These results pave the way for the realization of solid‐state lasers exploiting various amplification routes based on organic crystals. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh130225qt" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
