We report on a first experimental demonstration of locking a doubly-resonant Fabry-Perot cavity to burst-mode picosecond ultraviolet (UV) pulses by using a temperature controlled dispersion compensation method. This technique will eventually enable the intra cavity power enhancement of burst-mode 402.5MHz/50ps UV laser pulses with a MW level peak power required for the laser assisted H− beam stripping...
A single frequency, mode hoping free, narrow linewidth laser system has been developed to generate high repetition rate picosecond UV pulses with MW peak power. Preliminary measurements have shown the generation of 402.5MHz/80ps pulses at high extinction ratio and single frequency operation. The laser parameters are promising in the application of laser assisted H− beam stripping at the Spallation...
Dual color beam recycling optical cavity was proposed to provide 402.5MHz 50ps UV laser pulses with a MW level peak power applicable to the laser assisted H-beam stripping for the Spallation Neutron Source.
Many laser applications in high energy physics require an enormous average laser power that is several orders of magnitude higher than what is available from the present laser technology. This paper reports the development of a macropulse mode laser system and a power recycling dual-wavelength optical cavity. The proposed technology has a capability of providing 50 ps/402.5 MHz/1 MW peak power UV...
In this study, refractive index variation in injection‐molded polymethylmethacrylate optical lenses under different levels of packing pressure was evaluated using a Shack–Hartmann wavefront sensor‐based metrology system. The experimental results showed that optical polymer's refractive index exhibits a considerable amount of variation for the lenses molded under different packing pressures. Specifically,...
A 5 × 5 micro Alvarez lens array mold was fabricated using a 5-axis ultraprecision diamond machine and an Alvarez lens array was manufactured by injection molding process. Unlike conventional processes for asymmetrical element fabrication such as small tool grinding, this research demonstrates slow tool servo broaching process that allows the entire Alvarez lens array to be accurately machined on...
