900nm High-Performance Band Tunable Diode Laser
The 900nm High-Performance Band Tunable Diode Laser is a high-end laser light source based on the Littman type external cavity architecture design, achieving ultra-low amplification spontaneous emission (ASE) output through a unique noise suppression design. It can achieve continuous tuning without mode skipping and with high spectral purity over a wide wavelength range, and provides high-power free-space output and flexible fiber coupling options. It is an ideal light source for fundamental research fields such as atomic physics, quantum optics, and precision spectral measurement.
