Abstract
Various embodiments of a multi-laser system are disclosed. In some embodiments, the multi-laser system includes a plurality of lasers, a plurality of laser beams, a beam positioning system, a thermally stable enclosure, and a temperature controller. The thermally stable enclosure is substantially made of a material with high thermal conductivity such as at least 5 W/(m K). The thermally stable enclosure can help maintain alignment of the laser beams to a target object over a range of ambient temperatures. Various embodiments of an optical system for directing light for optical measurements such laser-induced fluorescence and spectroscopic analysis are disclosed. In some embodiments, the optical system includes a thermally conductive housing and a thermoelectric controller, a plurality of optical fibers, and one or more optical elements to direct light emitted by the optical fibers to illuminate a flow cell. The housing is configured to attach to a flow cell.
