<p>Cyclobutenediylium dyes for passive optical switch for gaint impulse laser for generation high efficiency light impulses have generally formulae (I) and (II): (in which R is a CH-acid substid. gp. esp. a cycloimmonium gp. R = CH(=CH-CH)n = where n is 0 or 1, R1 is alkyl, aryl, aralkyl or hydroxyalkyl, and Z are atoms needed to complete 5- and 6-membered opt. substd. and/or annulated heterocyclic ring systems, or a substd. phenyl gp) and absorption wave length can vary with R and/or solvent used.</p> |
