ANDO AQ4321D可调谐激光源具有绝对波长校准功能,使用内部气体电池吸收线。该校准功能提供高精度、可靠的DWDM组件测量。AQ4321D的内部设有一个精密电机,通过控制亚微米级光栅的位置来实现波长调谐。光输出的一部分被提取出来并通过参比气体单元进行波长偏移校准。为了确保长期的高波长精度和高输出稳定性,AQ4321D的光模块由一个光探测器持续监测; 此外,自动功率控制电路用于保持非常高的输出稳定水平。
特点:
The Ando AQ4321D Tunable Laser Source features an absolute wavelength calibration function that uses an internal gas cell absorption line. This calibration function provides highly accurate, reliable measurements on DWDM components. The interior of the AQ4321D features a precision motor that achieves wavelength tuning by controlling the position of optical grating at the sub-micron level. A portion of the optical output is extracted and goes through the reference gas cell for wavelength offset calibration. To ensure long-term high wavelength accuracy and high output stability, the optical module within the AQ4321D is constantly monitored by a photo detector; also, an automatic power control circuit is used to maintain very high stability in output level.
