快速可調諧激光器1520-1575nm 30mW輸出功率
The RTL-1550 is a sweep laser source that is capable of rapid wavelength tuning across the expanded C-band (1520nm to 1575nm) wavelength windows. Driven by an functional generator, such as DS335 by Stanford Research, it can produce dynamically scanning wavelength spectrum up to the rate of 2.5 kHz. RTL-1550 provides excellent Side Mode Suppression Ratio (SMSR) of 50dB and high output level of 30mW. These performance enables excellent signal-to-noise ratio in Fiber Bragg Grating (FBG) sensor interrogation system, optical coherence system and optical frequency domain ranging.
Applications:
Optical coherence tomography
FBG sensor interrogation systems
Fiber Optics device characterization
Part Number: RTL-1550-30
