•    488 nm, 20 mW
•    ≤1% power stability
•    TEM00 beam

Klastech GmbH has launched the DENICAFC 488-20 solid-state laser, which emits a single-frequency laser beam at 488 nm with output powers up to 20 mW.

Based on proprietary double-enhanced intracavity frequency conversion (DENICAFC) technology, the system offers high performance. Target applications include CD mastering, confocal microscopy, digital film processing, ellipsometry, flow cytometry, holography, interferometry, metrology, molecular biology, printing and reprographics.

According to the company, advantages of the technology include its high reliability and its insensitivity to ambient influences. This is supported by the optical layout as well as by automatic stabilization of output parameters. As a result, the laser delivers a single-frequency output without mode hops, and with stable low-noise operation. Power stability over 4 h and optical power noise are specified at ≤0.3% and ≤1% rms, respectively.

The laser design supports scalability and high efficiency, with more than 20% of the input power being converted into optical output. The spatial beam quality is diffraction-limited; i.e., TEM00 with an M² <1.05. Thermal management is implemented via thermoelectric conductive cooling, enabling the 123 × 64 × 57-mm laser head to be operated on a solid metal surface of 150 × 210 mm and having a thickness of 10 mm or greater.
