ZFA-R-405 Narrow Linewidth Diode Laser

The ZFA-R-405 Narrow Linewidth Diode Laser provides highly stable emission at 405 nm with ultra-narrow spectral linewidth and excellent beam quality. Designed for precision measurement and spectroscopic applications, this CW laser delivers output powers up to 50 mW with near TEM00 transverse mode and spectral linewidth below 0.06 nm (optional <0.03 nm). With superior wavelength stability, excellent beam quality (M² <1.5), and high polarization ratio (>50:1, optional >100:1), this laser is ideal for high-resolution spectroscopy, Raman analysis, fluorescence excitation, and advanced optical research. Its compact, reliable design and long operational lifetime of 10,000 hours ensure consistent performance in laboratory and OEM environments.
