Investigation of Double the Optical Angular Multiplexing System for “Heaven” Facility
The “Heaven” facility is the maximal high power krypton-fluoride (KrF) excimer laser in our country. It is composed of an excellent beam profile amplified spontaneous emission (ASE) source, a discharge pumped KrF laser, two stage two-electron-pumped KrF amplifiers, six beams optical angular multiplexing system for beam smoothing, physical diagnostic system, etc. The facility can produce six beams, more than one hundred joule energy, 248 nm wavelength, 23 ns width laser pulse. This paper introduces a method and technology research of double the optical angular multiplexing system for “Heaven” facility. The main contents are as followed: the method of producing 10 ns pulse, the principle introduce of polarization beam split,and the design scheme of twelve beams angular multiplexing system.
