Please log in for more thread options undersea cable. Because the range is very long the used laser source must have low wavelength drift. I choose the external cavity laser diode (with <10KHz) as the laser source. And i want to know how to measure its short-term wavelength drift, anyone can give me some suggestions? Where can i buy such a laser? Or any other laser sources can be used in my project? Thank you in advance. | ||||||||||
