The LASOS® Ar-Ion lasers cover a broad spectrum in the blue and green spectral range, with emission lines from 454 nm to 514 nm, in single wavelength and multiwavelength versions with output powers up to 225 mW. For photo printing applications in the AGFA d-lab.2 and d-lab.3 printers a dual line laser with emission at 454 / 458 nm and 514 has been developed, showing an excellent beam quality, beam pointing stability and long-term stability with low noise operation.

All laser tubes have an internal mirror vacuum-tight hard-sealed and integrated resonator construction optimizing the life time and power stability. The laser mirrors are adjusted and fixed by a special, proprietary technology providing maintenance-free operation and no need for readjustment in the field. The LASOS® laser modules are compact, economical and are available with several cooling options. All laser models can be provided with OEM power supplies, designed to meet the European and American standards with availability of approvals and certificates CDRH, IEC, CDA, CE, TÜV, UL.

Customized solutions for specific applications as well as a fiber coupling option are available. For particular models a tube exchange is available.
