Diode laser stack family

1200 W diode laser stacks

The public 1200 W text lists stacks whose bar count and power per bar multiply to 1200 W, mostly 12 × 100 W, with 808 nm and mixed maps. Several headings are series names rather than a unique model code. Identical text rows are shown once, with every catalog page number kept.

Source checked 7 November 2026: public catalog page. Chip names describe bars in that catalog. They are not a claim that Hangzhou SG manufactures those chips.

Photographed module Q2785

Bare diode laser stack photographed with markings Q2785 and LT-00MH001200N
Public photograph from the Q2785 section of the 1200 W page. The page says the unit carries both markings. Other digits visible on the metal are not defined in that text, so they are not added as ratings.

The public page calls this an unhoused 1200 W diode laser stack. It also says the sales-SKU-to-manufacturer-model mapping is not confirmed beyond the markings on the photographed unit, and that drive current, cooling, FAC, dimensions, connector layout and compatibility are not established. The reference price on that page is not repeated.
