Efficient Tunable Visible Laser Source.
Abstract
In this final report, we summarize the design and performance of an optically phase-conjugated tunable visible dye laser system, and the frequency doubled Q- switched Nd:YAG laser used to drive it. This high-brightness laser source utilized optical phase-conjugation (OPC) via Stimulated Brillouin Scattering (SBS) in a double-passed dye laser cell containing Rhodamine 6G in methanol. The dye cell it-self served as the SBS active medium. The use of SBS to remove optical abberrations in laser systems is relatively well-known; the implementation described herein is unique and can be used to provide a very compact tunable laser source. We have produced a 561 improvement in beam brightness and a 2.74 times improvement in beam jitter using the SBS in the double passed amplifier over using an ordinary retro mirror. This increase in beam brightness is due to a significant improvement in beam quality, and some pulse compression, obtained by using SBS. Output energy/pulse of 23 mJ has been demonstrated at 10 Hz and 560 nm output wavelength; tunability from 554 to 574 nm has also been demonstrated. jg
