Abstract
A fiber laser source is configured with a plurality of individual fiber lasers which are coupled to one another in series. Each subsequent fiber laser is configured to transmit laser radiation of any of fiber laser or lasers located upstream therefrom. The switching among different operational regimes of the laser source, which includes SM, MM and different MMs and associated therewith beam shape, beam quality and power parameters is provided at high frequency corresponding to on/off switching of each individual fiber laser.
Claims17
A fiber laser source comprising:
- upstream and downstream fiber lasers optically coupled to one another in series and controllable to generate respective first and second beams, the downstream fiber laser being configured to transmit a first beam, wherein the first and second beams each are characterized by a parameter including a beam shape, beam quality, power, wavelength or a combination thereof;
- and
- a delivery fiber optically coupled to an output of the downstream fiber laser and configured to transmit the first beam or the second beam or the first and second beams simultaneously.
