High-Performance Narrow-Linewidth Solid-State Organic Lasers

These compact dispersive laser oscillators have been shown to yield beam divergences ~ 1.5 times the diffraction limit and single-longitudinal-mode emission at laser linewidths of ~ 350 MHz. Emission pulses are in the ns regime at peak powers in the kW range. Continuous tunability has been demonstrated in the 550-600 nm region.




Solid-state organic laser incorporating a dye-doped-polymer gain medium in a multiple-prism near grazing-incidence grating oscillator configuration. This oscillator is excited longitudinally (from Duarte, 1997).

Coherent Electrically-Excited Organic Semiconductor Interferometric Emitters


The search for the electrically-excited organic laser has a long history. These three papers report on the first successful observation of coherent emission from electrically-excited organic semiconductors. The gain medium in these interferometric emitters is the laser dye coumarin 545 tetramethyl. The emission is generated in a miniature, sub micrometer, resonator. The emission beam is nearly diffraction limited and the spectral linewidth has been determined, using interferometric means, to be ~ 11 nm (at half width) which approximates the linewidths available from broadband dye lasers. Work is in progress to elucidate the origin of the observed coherence.
