…typical, individual diode laser emitter might produce at most a few
watts (~5-15 W). However, a well-established modular architecture enables easy scaling to high
powers. For example, numerous emitters can be fabricated on a single monolithic
semiconductor array or bar with a total…

…environment. For laser output power ranges in the tens and hundreds of milliwatts, cooling starts to become more important, especially for lasers that require good control of beam quality--here, thought given to heat-sink design is a benefit. For cooling of small diode Laser diodes work best when…

diode lasers offer the lowest capital cost of any industrial
laser type, as well as the lowest operating costs, due to their high electrical efficiency. On the downside, high-power laser diodes or arrays cannot deliver
anything close to the diffraction-limited beam provided by other laser
