Pulse-charging coupling laser apparatus

Abstract

Abstract An improved laser apparatus is disclosed which employs a pulsecharging coupling connected in circuit between a pulse generator means and an excitation medium which is employed to excite a laser material to a lasing level. The laser disclosed preferably comprises a source of electrical power, a pulse generator which may take the form of a pulse-forming network together with a switch means, and an appropriate form of pulse-charging coupling connected between the pulse generator and the medium which is to be excited to raise the lasing material to a lasing level. The pulse-charging coupling performs the function of impressing pulsed electrical energy upon a medium such as gas, for example, with significantly improved efficiency to optimize the lasing phenomenon. The concept of the disclosure which teaches the use of a pulse-charging coupling is readily adapted to, and ideally suited for employment in producing the most favorable impedance matching relationships of the laser apparatus which in itself contributes significantly to the efficiency of the transfer of energy from an electrical power source to produce optimized laser power output. Several forms of pulse-charging couplings are disclosed and described including a flat, parallel plate type which may comprise a dual ground plane and transmission line portion; a multiple conductor coaxial form of pulse-charging coupling is also described and illustrated in the disclosure.
