Summary
This study investigated ablative wall flashlamps for high peak power dye lasers. Xenon proved superior for pumping, especially at higher energy densities.
Area of Science:
- Laser Physics
- Optical Engineering
- High Energy Density Physics
Background:
- Ablative wall flashlamps are crucial for pumping high peak power dye lasers.
- Optimizing flashlamp performance requires understanding gas type and energy density effects.
Purpose of the Study:
- To experimentally investigate ablative wall flashlamps for pumping high peak power dye lasers.
- To measure emission spectrum, brightness, and efficiency across different tube diameters and energy densities.
- To compare the performance of xenon and air as fill gases.
Main Methods:
- Experimental setup using three flashlamp tubes (1.6 mm, 4.4 mm, 8 mm diameters).
- Measurements of spectral emission, brightness, and efficiency from 250 nm to 580 nm.
- Varying electrical energy input densities up to 560 J/cm(3) with xenon and air.
Main Results:
- Flashlamp duration was approximately 2 microseconds.
- Xenon consistently outperformed air across tested parameters.
- Above 150 J/cm(3), gas type and pressure became less critical, but xenon remained superior.
Conclusions:
- Ablative wall flashlamps are effective for high peak power dye laser pumping.
- Xenon is the preferred fill gas for optimal flashlamp performance.
- Energy density significantly influences flashlamp output, with xenon showing consistent advantages.
