ZFA-V-660 – Diode Laser at 660 nm

The ZFA-V-660 long coherent length diode laser provides a stable 660 nm output with exceptional beam quality, high coherence, and reliable operation for demanding scientific, industrial, and research applications. Designed for continuous-wave (CW) operation, it delivers output power up to 120 mW with near TEM00 beam profile, making it ideal for high-precision optical systems. With a coherence length exceeding 1 meter, low beam divergence (<1.5 mrad), and M² factor <1.5, the ZFA-V-660 ensures excellent spatial coherence and beam uniformity. High power stability (<1% RMS over 4 hours) guarantees consistent performance for sensitive measurements and experiments.
