The Stockholm-based start-up Comlase is developing a 980nm pump laser which requires no cooling. The company plans to invest in a laser production plant and has its eyes on a substantial share of the market.
Comlase is the first Swedish company to develop its own pump laser. Lasers of this kind are used in erbium-doped fibre amplifiers (EDFA) and the newly formed company is developing a pump laser for 980nm, which is the most common type. However, Comlase's laser is special in that it operates without having to be cooled. This makes it less expensive and easier to build into the fibre optic network.

The company is still very secretive and has not yet been officially launched. However, Elektroniktidningen has talked to sources close to the company and can reveal that Comlase has imminent plans to invest some SEK 300m to 400m. A production plant for the lasers should be operational next year. With a new production process, the company expects to achieve a power output which is greater than for existing pump lasers.

The world market for 980nm pump lasers is expected to reach SEK 27bn in 2004 and Comlase is hoping to control between 10 and 20 per cent of this market by 2005 or 2006. That is, if everything goes according to plan.

Heading the company are two prominent Swedish laser and EDFA experts, Carsten Lindström, formerly of Geotronics, and Peter Blixt, who has left Ericsson Microelectronics.
