ABOUT

 The invention relates to quantum electronics and can be used to create compact and reliable ion lasers of continuous action on inert gases with increased radiation power,

The aim of the invention is to increase the reliability and decrease the material consumption of the laser.

; The drawing shows an ion laser: on inert gases with a power supply circuit, j The ion laser on inert gases contains an active element 1 with a cathode. 2, anode 3 and water cooling jacket A, a solenoid in the form of two sections 5,6 having a multilayer cylinder covering the active element: the primary winding and the terminal time terminal, the ignition electrode 7 in the form of the cooling jacket section i located in the gap between the solenoid sections i, the power source 8 in the I form as a symmetric suprameter with a ground midpoint, connected to the anode and cathode of the active element, and the ignition transformer 9.

The windings of the sections of the solenoid are placed in the covers 10 of nickel foil. The initial and final outputs of each winding are brought to the ends of the solenoid sections facing each other. In this case, the initial windings of the windings are located closer to the surface of the active element than the final ones, and are connected to the cathode and the anode. The final windings are interconnected. One of the conclusions of the secondary winding of the ignition transformer is connected through the ballast resistance 11 to the ignition electrode, and the other electrode is connected to the initial terminal of one of the solenoid windings. The primary winding is low. frequency step-up transformer 9 ignition is connected through the switch 12 to the industrial network of the re-. current frequency of 50 Hz, voltage 220-380 V "Mirrors of the optical resonator 13 are used to receive and output 1 laser radiation in a working laser

The ion gas laser operates as follows.

The cathode and the anode of the active element, filled, for example, with argon up to a pressure of 0.8-1 mm. S, supplies the voltage from the power supply 8, which, after connecting the ignition transformer to the industrial network

alternating current initiates a discharge in the active element. This discharge excites argon atoms with the formation of the inverse population of laser levels, which results in the generation of laser radiation in an optical resonator. The supply voltage is also supplied to the initial outputs of the solenoid windings, which leads to the formation of a longitudinal magnetic field in the solenoid. With the length of the discharge capillary of the active element of 1 m and its 2.5 m diameter, the voltage at the anode from a symmetric rectifier with a grounded midpoint is - --ZOO B, and at the cathode (-300) B, for example The magnetic field in the active element reaches 1200-1500 E.

Placing the solenoid windings in nickel-foil covers allows the heat generated in the windings to be effectively removed into the cooling fluid circulating in the gap between the cover and the section casing, which makes it possible to reduce the size, weight and material intensity of the ion laser and increase; its reliability.

Placing the leads of the solenoid windings between its sections and connecting the rectifier to the initial leads allows an increase in the reliability of the laser since the final leads of the windings. the solenoid is removed from the electrodes — the anode and cathode of the active element, which are at a high potential. Since the initial leads are located closer to the active element and bordering the inner surface of the windings, which is 2-2.5 times smaller than the outer surface, the main heat sink from the winding occurs through the outer surface of the solenoid sections. Since the inner surface is covered with more reliable electrical insulation, and at the final terminals of the windings the voltage relative to the nickel foil and the body of the solenoid is almost O, the likelihood of a solenoid being almost eliminated and the reliability of the laser as a whole increases significantly.

A significant advantage of the ionic laer is also that it does not interfere with the computing technology and the electronic automa- tion systems that are used & 1 with technical installations. This is the advantage of St. 314

It is connected with the absence of steep current fronts and voltages when initiating a discharge in the active element of a laser with an ignition transformer, connected to the firing electrode at the initial output of one of the windings via ballast resistance and fed from an industrial AC network.

The invention can be used in the development of high-power argon and krypton lasers in the visible and UV spectral ranges used in technological installations in microelectronics for the manufacture of primary photomasks and integrated microscopes in the optical industry for the manufacture of holographic optical elements.
