VALO SHG SF is a unique tunable single-frequency VECSEL system with efficient intracavity second harmonic generation. This newly developed laser is currently available between 400–700 nm with watt-level output power and uses the same turnkey VECSEL platform as our near-infrared VALO SF product line.

VALO SF is a single-frequency VECSEL system that combines a unique set of laser properties in a compact package; namely high-power continuous-wave operation (1–4 W CW), narrow linewidth (~100 kHz), broad tuning (~10 THz), and excellent beam quality (M2<1.1). The selection of center wavelengths in-stock covers wide spectral range in the near infrared between 800–1400 nm & 1950–2150 nm. Other wavelengths between 1400–1950 nm and in the 700–800 nm range are under development and available on request.

The system includes a VECSEL head with integrated pump laser, a control unit and a low-vibration chiller. Output powers >10 W can be reached with external pump laser. It is possible to retrofit a different gain chip in the VECSEL head later, to adapt the system to the changing needs of the research environment.

We provide high-power VECSEL gain chips on submounts for R&D laser systems in research and industry. The selection of wavelengths in-stock covers wide spectral range in the near infrared between 800–1400 nm & 1950–2150 nm with output powers up to 70 W. Other wavelengths outside this range are also available on request.
