633nm 20mW Single Mode Fiber FP Laser System CW/TTL Modulation/Analog Modulation with SMA905 Connector
AM633MFB20X Laser System
The AM633MFB20X is a high-performance 633nm single-mode laser system for precision applications in biomedical imaging, metrology, and scientific research. Featuring exceptional beam quality, narrow spectral width, and high coherence, it is an ideal alternative to traditional helium-neon lasers or high-end semiconductor sources.
This system integrates a Fabry-Pérot laser diode with single transverse and longitudinal mode output, delivering stable power up to 20mW. The laser is fiber-coupled with armored protection, supporting multiple connector options (FC, SMA905, SC, ST). Air cooling and automatic current control (ACC) ensure long-term operational stability, while optional TTL and analog modulation offer flexible integration into advanced systems.
