Agile solid state dye lasers

Different organic dye molecules were incorporated in solid gels by the sol gel process with a view to develop tunable solid state laser applications. We studied the laser emciency of these materials by using a nanosecond frequency doubled Nd:YAG as the pump laser. Slope emciency up to 30 % with 3 mJ output energy and half energy lifetime of 40,000 shots were thus obtained. This large lifetime w...

From Flashlamp-Pumped Liquid Dye Lasers to Diode-Pumped Solid-State Dye Lasers

Dye-laser technology has seen very significant progress over the last 39 years since the first demonstration of this device technology. Dye lasers offer efficient emission in the visible and near-infrared bands by direct generation of laser light. The initial emphasis was on the liquid-phase technology, and is the one very successful liquid laser. More recently the research emphasis has been so...

Reconfigurable Solid-state Dye-doped Polymer Ring Resonator Lasers.

This paper presents wavelength configurable on-chip solid-state ring lasers fabricated by a single-mask standard lithography. The single- and coupled-ring resonator hosts were fabricated on a fused-silica wafer and filled with 3,3'-Diethyloxacarbocyanine iodide (CY3), Rhodamine 6G (R6G), and 3,3'-Diethylthiadicarbocyanine iodide (CY5)-doped polymer as the reconfigurable gain media. The recorded...

Photostability of luminescent dyes in solid-state dye lasers

Fluorescence photobleaching was measured in dye-impregnated sol–gel/polymer composite glasses. These fluorescent glasses were used as the gain medium in a transverse-pumped solid-state dye laser. In this configuration, the fluorescent glass was excited by a pulsed Nd:YAG laser (about 6 mJ/pulse) either while placed in an optical cavity (i.e., functioning as a pulsed laser) or with the optical c...
