HIGHLY EFFICIENT ORGANIC LASER EMISSION

This is a brief guide to the literature of efficient organic lasers. The papers and books included here refer to efficient solid-state organic gain media as well as narrow-linewidth tunable laser oscillators engineered using efficient organic gain media. As a reference point it should be indicated that the efficiency of well-designed standard laser-pumped organic dye laser systems is known to reach the 50-60% range (see, for example, Dye laser Principles or High-Power Dye lasers). In fact, good efficiency in the generation of high-power tunable visible radiation is one of the well-known advantages offered by dye lasers.

However, in the recent literature some language inflation has transformed the adjective "efficient" into "highly efficient." Thus, "good efficiency" should be equivalent to "high efficiency" and so on. Hence, in the interest of equivalence we have entitled this publication using contemporaneous language.

High-Performance Narrow-Linewidth Solid-State Organic Laser Oscillators

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.

In these solid-state tunable lasers the gain medium is an organic-dye-doped polymer matrix. Usually this matrix is a highly homogenous form of poly(methyl-methacrylate) (PMMA). An additional example of a polymer used as matrix in the gain media of a tunable polymer laser is HEMA:MMA.
