GV-721
The GV-721 is a high-precision 721 nm fiber-coupled laser system integrating the laser diode, fiber-coupled optics, power supply, and temperature control into a single compact housing. Delivering continuous-wave (CW) output powers from >1 mW up to 450 mW after fiber, it ensures high stability, fast warm-up, and optional TTL or analog modulation.
Its air-cooled design, broad operating temperature range, and long expected lifetime make the GV-721 ideal for medical, biomedical, and industrial applications that require precise, reliable, and stable near-infrared illumination.
