…ultrafast fiber lasers. These lasers use a diode-pumped optical fiber with an integrated mode-locking
mechanism to produce 100-fs to 10-ps pulses with wavelengths around 1 mm, while fiber lasers based on Er produce wavelengths around 1550 nm and are now
a common staple in optical fibers…
…NORIA tool can shift FBG center wavelength
as much as 4 nm (for a phase mask nominally centered at 1550
nm) using pretensioning, which is more than twice what is necessary to correct for the typical batch-to-batch variations in fiber NA. Control of the pretensioning force is precise enough…
