1. A compact, thermally stable multi-laser system, comprising:

  • a plurality of lasers outputting a plurality of respective laser beams;

    a beam positioning system configured to position the plurality of laser beams closer together;

    beam focusing optics configured to focus the plurality of laser beams;

    a thermally stable enclosure enclosing the plurality of lasers, the beam positioning system, and the beam focusing optics, and configured to thermally and mechanically couple to a flow cell, said thermally stable enclosure substantially comprising a material with high thermal conductivity of at least 5 W/(m K), and having a volume of 36 cubic inches or less; and

    a temperature controller configured to control a temperature of said enclosure and flow cell and to align the focused laser beams to the flow cell over a range of ambient temperatures.
