摘要： PURPOSE:To set up the criterion representing the optical auxiliary ionization timing substituting for laser output for making the highly efficient oscillation step feasible by a method wherein the auxiliary ionization timing is set up within the range wherein the auxiliary ionization timing point is contained in the duration of the auxiliary ionization step. CONSTITUTION:The title discharge excited pulse laser device adopts the corona auxiliary ionization system for auxiliary ionizing a laser gas by the ultraviolet rays emitted from corona discharge. The auxiliary ionization step can be assumed to be performed while a current is running in the auxiliary ionizing part so that the pulse width of a current wave form may represent the duration of the auxiliary ionization. At this time, T1 represents the auxiliary ionization timing when the terminal point of a pulse current is equalized to T0 while T2 represents the auxiliary ionization timing when the starting point is equalized to T0. At this time, the auxiliary timing minimizing the discharge starting voltage (c) is contained in the duration of the auxiliary ionization. Through these procedures, the optimum auxiliary timing can easily be set up simply by measuring the discharge starting voltage (c).

摘要： PURPOSE:To improve a discharge pumped laser device in efficiency by a method wherein a current return conductor is arranged on the side face of a cooling vessel where a thyratron is provided. CONSTITUTION:When a thyratron 4 is turned ON, the change stored in a storage capacitor 3 is started transferring to a peaking capacitor 5, and a return light is made to return to the thyratron 4 from the ground potential terminal of the peaking capacitor 5 passing through a laser chamber 7 and a current return conductive plate 12. At this point, as the current return plate 12 is provided to the side face of a thyratron cooling vessel 9, the area A of a part between the current return conductive plate 12 and a cover 6 is independent of the structural inductance L of this closed loop. Therefore, a voltage V2 between the ends of the peaking capacitor 5 can be enhanced in rise by decreasing this structural inductance L. By this setup, a gas laser device of high efficiency, where a structural inductance contained in a circuit for discharge-pumping is small, can be obtained.

摘要： PURPOSE:To obtain a laser having good coherence, intensity distribution having no hole or skirt and good availability by providing an output mirror having a uniform reflectivity over a whole surface to be irradiated with a laser beam, and apertures disposed at a total-reflecting mirror and output mirrors. CONSTITUTION:At least one surface of an output mirror 1 has a curvature R1, and is so finished that the reflectivity of the surface uniformly becomes r. A total-reflecting mirror 3 has a curvature R2 to form an unstable type resonator through an exciting space 4 together with the mirror 1. A laser beam 5 is amplified while it reciprocates in the resonator, thereby oscillating. Apertures 7a, 7b for limiting the diameter of the beam are disposed near the mirrors 1, 3. The apertures 7a, 7b cut the reflected lights from the electrodes and the like and so regulated as to obtain as many lights as possible from a space to be uniformly excited.

摘要： PURPOSE:To increase regions wherein preparatory ionization is performed and lengthen a discharge gap, by providing auxiliary electrodes performing preparatory ionization respectively on the rear parts of the first and second main discharge electrodes of a discharge-pumped short-pulse laser device. CONSTITUTION:A high-voltage pulse power supply 6a impresses high-voltage between an anode 3a and a metal electrode 5a, while a high-voltage pulse power supply 6b impresses high-voltage between a cathode 3b and a metal electrode 5b respectively. In the opening parts 7, 7 provided on the anode 3a and the cathode 3b, creeping discharge is generated along the dielectrics 4a and 4b. A part of electrons generated by this discharge and the electrons to be photoionized by ultraviolet rays generated by discharge become the species for making the main discharge a uniform discharge in a glow state. Preparatory ionization regions 9a and 9b preparatory-ionize the peripheries of the anode 3a and the cathode 3b respectively. Next, when high-voltage from a high-voltage pulse power supply 1 is impressed between the anode 3a and the cathode 3b, the uniform main discharge 8 in a glow state is generated.
