IdealPhotonics' near-infrared tunable laser is a laser system whose wavelength can be continuously or steppedly adjusted within the 700-2500 nm range. It achieves high-resolution wavelength output through techniques such as external cavity grating tuning, semiconductor current tuning, or nonlinear frequency conversion, combining wide spectral coverage with rapid switching capabilities. It is specifically designed for applications such as spectral analysis, biological imaging, and fiber optic communication.Through tuning mechanisms such as external cavity grating/current injection, it achieves precise wavelength control with nm-level resolution in the 700-2500 nm band, combining wide spectral coverage, millisecond-level switching speed, and high output stability, making it a core light source tool for molecular spectroscopy detection, OCT medical imaging, and photonics research.
