Focuslight Technologies will be presenting its FL-VS300 series of semiconductor lasers at booth 1855.

These lasers are high-power, high-reliability, low-smile-effect laser bars based on micro channel cooling (MCC). Designed for volume production, they feature a laser bar bonded on MCC with AuSn (gold-tin) solder, which results in a low smile. A 1cm bar with less than a 1µm smile can deliver more than 200W continuous wave (CW) output, with a power conversion efficiency of 65 per cent and a lifetime of more than 20,000 hours. Power can be scaled to a few kilowatts in CW mode using vertical stacks. 

These high-power and low-smile vertically stacked laser diode bars are ideal for demanding applications such as forming a wider line for glass surface treatment, or a rectangular beam for cladding.
