Does anyone know if it is possible to design an excimer laser that produces a continuous beam well into the UV frequency range (enough to througly ionize the air in the path of the beam). I have been reading up on excimer lasers and it sound like they operate in pulses, which may be ok for the experement I am trying to set up but would prefer continuous.
Does anyone know of any texts that have detailed designs of excimer lasers. I have heard that the flash tube has to be capable of handling up to 5 bars of pressure and high temperatures due to the nessicary frequencies of the elecrical pulses that are fed to the gas. I could design (hopefully) an oscelator to get the high frequency electrical signal but I was reading that the electrical contacts run the length of the flash tube in order to ionize the gas so this would be something that would need to be in the design spec of the glass tube.
Also can you buy XeF or the other nessicary gases, are they outragiously expensive? I am guessing that you can mix Xe and F in the flash tube and after the first use they will bond from the elecrical excitation since that's the only way to bond a noble gas as they are chemically inert. I am worried that you either can't buy these gases or they are cost prohibitivly expensive also are they toxic enough to kill you if the gas is released of if you screw up some how?
I was looking into just buying a UV laser but what I found was cost prohibitivly expensive (~30 grand). I was going to contact a glass company to see what it would cost to have the flash tube made but want to have specific design specs to make sure I get what I need before I spend any money.
