Abstract
Embodiments are directed to systems and methods for correcting lateral and angular displacement of laser beams within a laser cavity. For some embodiments, such systems and methods are used to correct angular displacement of laser beams within a laser cavity that result from varying the lasing wavelength in a tunable laser system.
Claims3
A method of angular stabilization of a beam path of a tunable laser, comprising:
- pumping a gain medium disposed within a laser cavity of a tunable laser system to generate a laser beam within the laser cavity having a first wavelength with a first beam path;
- tuning the laser system to a second wavelength which is different from the first wavelength and which exits the gain medium on a second beam path different from the first beam path;
- passing the laser beam of the second wavelength through at least one angular beam position correction element that refracts said laser beam to an optical path that is substantially parallel to first beam path.
