About this site

A category site for diode laser machines from Hangzhou SG Electronic Technology Co., Ltd.. Machines are organised by wavelength, power, series and cabinet style.

Only parameters that already appear in the company catalog or the local product folders are shown. Missing values are omitted, not invented.

This category site does not list prices. Ask for a quotation by WhatsApp or email, or see the machine mall.

Watt figures such as 500 W or 1,200 W are the catalog diode-stack or handpiece power, not the electrical input of the complete machine.

Some catalog rows use 780–790 nm bars. The source notes these are sometimes described elsewhere as 755 nm. This site lists 755 nm only where the catalog itself says 755 nm.

Diode stacks as parts belong on the stack site. Machine quotations can also go through the mall at https://www.sg-hz.com/single-function-diode/.
