Abstract
A laser system may include one or more of the following components: a power supply, a continuous wave pump laser, a fiber optic cable, a positive lens, a gain medium, a heat sink, and/or a Q-switch. The laser system may be used in a light detection and ranging (LIDAR) system such as a scanning LIDAR system. The laser system may be designed to operate at wavelengths that may be safe for human eyes.
Claims20
A laser system comprising:
- a power supply;
- a continuous-wave pump laser configured to receive power from the power supply and configured to generate a first laser beam;
- a gain medium comprising an input surface, an output surface, and an external surface, wherein the input surface is configured to receive the first laser beam from the continuous-wave pump laser, and wherein the gain medium is configured to generate a second laser beam and to emit the second laser beam via the output surface;
- a heat sink coupled to the external surface of the gain medium;
- and
- a Q-switch configured to receive the second laser beam from the output surface of the gain medium.
3 more elements
A laser head comprising:
- a gain medium comprising an input surface, an output surface, and at least one external surface, wherein the input surface is configured to receive a first laser beam from a pump laser, and wherein the gain medium is configured to generate a second laser beam and to emit the second laser beam via the output surface;
- a heat sink coupled to the at least one external surface of the gain medium;
- and
- a Q-switch coupled to the output surface and configured to receive the second laser beam from the gain medium.
1 more element
A positive lens for use in a laser apparatus, the positive lens comprising:
- a convex input surface configured to receive a laser beam from a pump laser and configured to focus the laser beam;
- and
- an output surface configured to transmit the focused laser beam to a gain medium.
