Alpes Lasers products

Alpes Lasers presents the Extended Tuning LaserQC-ET, a cutting-edge device designed to offer a higher degree of wavelength tuning versatility compared to standard DFB lasers. The QC-ET model enables continuous tuning across 0.4% of the central wavelength, utilizing dual current control for extended mode-hop free tuning exceeding 6 cm-1 at 1270 cm-1. Unlike conventional DFB lasers, it integrates a heater current, IT, that allows rapid wavelength adjustment, significantly faster than changes achievable through heatsink temperature alterations. This feature ensures enhanced scanning span that remains fully electrical, enabling wavelength dithers, ramps, and reproducibility akin to standard DFB lasers, while maintaining high-quality linewidth and low noise. This technology appeals to a technically advanced audience seeking sophisticated solutions for various applications in photonics.
