Изобретение относитс к квантовой электронике и может найти применение в системах космической и земной дальней св зи, а также передаче энергии на Землю с помощью лазерного луча.The invention relates to quantum electronics and can find application in space and terrestrial telecommunication systems, as well as the transfer of energy to the Earth using a laser beam.

Цель изобретени - повышение КПД.The purpose of the invention is to increase efficiency.

Схема лазера представлена на чертеже.The laser circuit is shown in the drawing.

Лазер содержит большое и малое зеркала системы накачки 1, 2, плоские зеркала 3-6, зеркала 7,8, образующие открытый резонатор , в котором размещен активный элемент 11. Позици ми 9 и 10 обозначены траектории прохождени солнечного излучени через лазер. Зеркало 3 расположено на одной оптической оси с зеркалом 2 подThe laser contains large and small mirrors of the pumping system 1, 2, flat mirrors 3-6, mirrors 7.8 forming an open resonator in which the active element 11 is placed. Positions 9 and 10 indicate the paths of the passage of solar radiation through the laser. Mirror 3 is located on the same optical axis with mirror 2 under

углом / 7j-(-4-+a), , где а - угол наклона ската крыши по отношению к оптической оси активного элемента, на торцах которого выполнены срезы в виде симметричных усеченных крыш. Зеркало 3 оптически св зано с первым скатом первого торца активного элемента 11, зеркало 4 установлено параллельно второмускату крыши первого торца активного элемента, зеркала 5, 6 установлены у второго его торца симметрично относительно его продольной оси и оптически св замы между собой и срезами этого торца. Все зеркала 3-6 размещены вне открытого резонатора.angle / 7j - (- 4- + a), where a is the angle of inclination of the roof slope with respect to the optical axis of the active element, the ends of which are cut in the form of symmetrical truncated roofs. Mirror 3 is optically coupled to the first slope of the first end of the active element 11, mirror 4 is mounted parallel to the second roof slope of the first end of the active element, mirrors 5, 6 are mounted at its second end symmetrically with respect to its longitudinal axis and optically coupled to each other and to the sections of this end. All mirrors 3-6 are located outside the open resonator.

Лазер с солнечной накачкой работает следующим образом. Излучение Солнца формируетс системой зеркал 1, 2, которое далее зеркалом 3 подаетс перпендикул рно на первый срез первого торца активного элемента Т1. Это излучение по траектории 9 проходит через активный элемент и падает на зеркало 6, а затем на зеркало 5, отразившись от которого по траектории 10 проходит через активный элемент и, отразившись,A laser pumped as follows. Radiation from the Sun is generated by a system of mirrors 1, 2, which is then fed by a mirror 3 perpendicularly to the first section of the first end face of the active element T1. This radiation along the path 9 passes through the active element and falls on the mirror 6, and then on the mirror 5, reflected from which along the path 10 passes through the active element and, reflected,

perpendicular to mirror 4: along the same path 10 returns to mirror 5, through mirror 6 along path 9 passes to mirror 3 and then scatters in the surrounding space. Thus, the solar pump radiation passes through the active element four times and excites optical radiation in it, which exits from the laser through one of the mirrors 7, 8. SUMMARY OF THE INVENTION A solar-pumped laser comprising a pumping system of two confocal multi-aperture mirrors optically coupled to an active element located in an open cavity along the longitudinal axis of the pumping system, two flat mirrors placed outside the laser optical cavity, the first of which is mounted on one optical axis with a smaller mirror of the pump system at an angle (p with respect to this axis and is optically coupled to the first end of the active element, the ends of the active element are cut off with respect to its the optical axis at

angle a, and angle f (), characterized in that, in order to increase the efficiency. Two additional mirrors are introduced, located outside the laser optical cavity, and the cuts at the ends of the active element are made in the form of symmetrical truncated roofs with an angle of inclination of the roof slope relative to the optical axis equal to a, the second flat mirror is installed parallel to the second slope of the roofs of the first end of the active element, additional mirrors are installed at its second end symmetrically with respect to its longitudinal axis and are optically coupled to each other and with slices this butt.
