…filters (<0.1nm) also requires the laser to have a very stable
wavelength. Non-stabilized diode lasers tend to be highly subject to mode hops which can shift the laser
wavelength outside the blocking range of the filters and result in either reduced Rayleigh suppression or a
PRINCIPLE OF OPERATION
The PowerLocker® acts as an ultra-narrowband, wavelength-selective
filter that provides stable, controlled optical feedback into the laser.
This increases the power in the desired mode and reduces unwanted
spectral components, reducing the linewidth of…
