    • Blue-Violet Band Semiconductor Laser

    The blue-violet band semiconductor laser series is a compact laser source designed for research, inspection, imaging, and spectroscopic analysis. The product covers major ultraviolet to blue wavelengths from approximately 375 nm to 488 nm, and offers various output powers, longitudinal modes, and modulation configurations to meet the light-source requirements of different experimental systems and industrial equipment. Standard wavelengths are available at 375±5 nm, 405±5 nm, 445±5 nm, 473±5 nm, and 488±5 nm, with some models supporting a wider selection. The series also includes low-noise versions and SLM (single-longitudinal-mode) versions to suit routine fluorescence excitation, high-stability detection, holography, and high-coherence optical experiments. The laser features a compact head design with an integrated TEC temperature stabilisation system, requiring no additional heat sink within the specified operating temperature range, making it easy to integrate into research instruments, detection equipment, and OEM systems.

    Product features：Wide wavelength selection；Multiple output power options；Low‑noise output；Good beam quality； Various modulation methods；Compact and easy for system integration

    Part Number：MP‑DL‑375‑060
