Изобретение относитс к квантовой электронике и может быть использован при создании дисперсионных резонаторов перестраиваег-шх лазеров.The invention relates to quantum electronics and can be used to create dispersive resonators for tuning lasers.
Известны способы перестройки длин волны излучени лазера, осуществл емые путем вращени пластинки внутри резонатора лазера 1, Известен также способ перестройки длины волны излучени лазера посредством нескольких интерферометров, включающий установку каждого из интерферометров внутри резонатора лазера до получени максимума пропускани интерферометров на одной длине волны 2. Способ перестройки, длины волны излучени лазера основан на установке всех интерферометров параллельно друг другу и перпендикул рно к оси резонатора , повороте одного из интерферометров относительно оси, перпендикул рной к оси резонатора до получени максиг/гума пропускани на одной выбранной длине волны и повороте каждого из оставшихс интерферометров относительно осей, параллельных указанной оси вращени первоначально повернутого интерферометра до получени максимума пропускани на упом нутой длине волны. Однако при переходеMethods are known for tuning the wavelength of laser radiation, carried out by rotating the plate inside the laser cavity 1, There is also known a method of tuning the wavelength of the laser radiation through several interferometers, including installing each of the interferometers inside the laser cavity to obtain the maximum transmission of the interferometers at one wavelength 2. tuning, the wavelength of the laser radiation is based on the installation of all interferometers parallel to each other and perpendicular to the cavity axis, turning those of one of the interferometers relative to an axis perpendicular to the axis of the resonator to obtain maksig / GUM transmittance at a selected wavelength and for each turn of the remaining interferometers about axes parallel to said axis of rotation of the interferometer initially rotated to obtain maximum transmission at said wavelength. However, on going
На другую длину волны излучени необходимо каждый из интерферометров устанавливать на максимум пропускани этой длины волны.At a different radiation wavelength, it is necessary to set each of the interferometers to the maximum transmission of this wavelength.
Дл упрощени способа перестройки длины волны излучени лазера предлагаетс предварительно осуществл ть поворот каждого из интерферометров отйосительно осей, перпендикул рных In order to simplify the method of tuning the wavelength of the laser radiation, it is proposed to preliminarily rotate each of the interferometers with respect to the axes perpendicular to
0 к оси резонатора лазера до получени максимума пропускани интерферометров на любой длине волны рабочего диапазона , а дальнейшую перестройку осуществл ть путем поворота интерферо5 метров на одинаковый угол относительно осей, проход щих через центры интерферометров и перпендикул рных к плоскост м, содержасдам ось резонатора и оси первоначального вращени .0 to the laser cavity axis to achieve maximum transmission of interferometers at any wavelength of the working range, and further restructuring by rotating interferometers at the same angle relative to the axes passing through the centers of the interferometers and perpendicular to the axes of the original rotation
