Abstract

We are offered and investigated the new-generation optical devices namely controllable lens-mirror objectives, which are designed for use in the modern laser engineering, including processing technologies. The one-channel deformable mirrors are used for design in the objectives. The objective's lens is arrange in the central hole of the main mirror and allows to optimize the objective's parameters. The controllable spherical deformations of the mirrors allow to change the objective's parameters and the charcteristics of the optical beam also, including in a real-time regime. The controlable lens-mirror objectives with focal distances of 200, 400, 602 and 800 mm are investigated. It is demonstrated that their efficiency is much higher than one of equivalent single deformable mirrors. In particular, the control range of the focal spot position is 1057 mm for the controllable objective with focal distance of 602 mm. It is 13 times more than the control range of the focal spot position using a single deformable mirror having the same focal distance. The obtained graphical curves have allowed to design the algorithms of synthesis of controllable objectives having the given parameters including maximum control range of the focal spot position.
