Abstract

Various embodiments of the disclosure relate to an optical system that includes a base unit and one or more cartridges that are removably attachable to the base unit. The one or more cartridges can include optical components configured to output a beam of light (e.g., a laser). The base unit can be configured to combine multiple beams of light (e.g., emitted by multiple cartridges) and output a combined beam of light. The cartridges can be interchanged to modify the light output by the optical system. The optical system can include thermally one or more stable enclosures and/or a temperature controller. The optical system can include one or more alignment adjustment optical components configured to adjust the alignment of one or more light beams.
