Modified polymeric matrices incorporating silicon atoms in their structure and doped with lasing dyes have been synthesized and demonstrated to render improved laser performance. When transversely pumped at 532 nm, highly stable laser operation with reasonable, not-optimized efficiencies was obtained. Materials were prepared where dyes pyrromethene 567 and pyrromethene 597 emitted laser radiation with no sign of degradation in the laser output, albeit with some oscillations, after 100 000 pump pulses in the same position of the sample at 10 Hz repetition rate.

    We report here the spatial distortion of a dye laser beam on propagation through a column of copper vapour. With the dye laser frequency tuned on the red side of the copper resonance line (578.2 nm), we have observed self-defocusing of the beam. This was caused by the resonant non-linearity...
