A formula for the diameter definition of the spot of focused laser emission at the known quality parameters of BPP and M2 ray is obtained. A formula for the definition of the optimum focal distance of an optical path in a fiber laser is presented. An alignment chart is formed for the definition of the optimum value of the focal distance of the optical system in a fiber laser.
