Laser
Selection of the laser
we used two single mode fiber coupled diode lasers with the wavelength of 488nm and 635nm in the setup. They were bought from openUC2. The output power of the laser are 30mW and 60mW.
Spectrum
Both laser spectrum is measured with spectrometer direct after the coupling fiber. Both lasers have nice peak wavelength with narrow band. The spectrum is shown as following:
The laser diodes are fabricated from Sharp. For the details about the laser diodes, there are datasheet available here
