Switch-less operation of a TEA CO2 laser

Opt Express. 2005 Nov 14;13(23):9636-8. doi: 10.1364/opex.13.009636.


We report here the operation of a UV pre-ionised mini-TEA CO2 laser where the use of an external switch has been dispensed with. This was rendered possible by making the preioniser spark array play a dual role- that of a switch as well as of a source of UV photons that pre-conditioned the inter-electrode volume.
