GV-690
The GV-690 is a high-power 690 nm fiber-coupled laser system integrating the laser diode, fiber-coupled optics, power supply, and temperature control within a single housing. Delivering continuous-wave (CW) output powers from >1000 mW up to 3000 mW after fiber, it provides excellent stability, fast warm-up, and optional TTL or analog modulation.
With air cooling, broad operating temperature range, and a long expected lifetime, the GV-690 is ideal for medical, biomedical, and industrial applications requiring precise, stable, and reliable near-infrared illumination.
