✦ Synopsis

Experimental and theoretical study of V-I characteristics of UV pre-ionized TEA CO 2 laser has been carried out for a variety of gas mixtures emitting different optical pulse shapes suitable for various applications. Coupled differential equations have been solved to model the pulse excitation circuit using the numerically calculated values of ionization coefficient (a), attachment coefficient (b) and drift velocity (U d ) as functions of E/N (i.e. electric field to neutral particle density ratio) for chosen gas mixture. Calculated and experimental V-I characteristics for gas mixtures (CO 2 :
