Abstract
Embodiments herein describe a path length adjuster for, e.g., adjusting the length of an optical cavity of a laser. In one embodiment, the path length adjuster includes a circulator element for ensuring unidirectional lasing. The path length adjuster may also include one or more focusing elements such as a focusing lens and/or a collimator which directs received laser light at a mirror. The mirror is mounted on an actuator that moves the mirror in a direction parallel with the propagation of the laser light, thereby increasing or reducing the length of the ring cavity.
Claims20
A cavity adjuster for a laser having a ring cavity, comprising:
- an input port configured to receive laser light;
- an output port configured to transmit the laser light;
- a circulator element optically coupled to the input and output ports and is configured to establish unidirectional lasing such that the laser light can propagate in the ring cavity in only one direction;
- a mirror configured to receive the laser light in free-space from the circulator element and reflect the laser light such that the reflected laser light passes through the circulator element and into the output port, wherein there is no optical fiber between the circulator element and the mirror;
- and
- an actuator physically coupled to the mirror, wherein the actuator adjusts a relative distance between the mirror and the circulator element to change a length of the ring cavity.
An optical path length adjuster, comprising:
- an input port configured to receive laser light;
- an output port configured to transmit the laser light;
- a circulator element optically coupled to the input and output ports and is configured to establish unidirectional propagation of the laser light from the input port to the output port;
- a mirror configured to receive the laser light in free-space from the circulator element and reflect the laser light such that the reflected laser light passes through the circulator element and into the output port, wherein there is no optical fiber between the circulator element and the mirror;
- and
- an actuator physically coupled to the mirror, wherein the actuator adjusts a relative distance between the mirror and the circulator element.
