VLM Series, up to 20 W

Visible CW Fiber Lasers

VLM Series is a family of highly-efficient, single-mode, visible CW fiber lasers with output powers up to 20 W. Customers can select a central wavelength in the range 515-635 nm. VLM series lasers are based on IPG's efficient and reliable fiber laser technologies and feature a super-compact lightweight optical head, connected with a fiber cable to a small air-cooled control module. The all fiber construction allows for full range of output power without changes in power stability and beam mode parameters.
