1550 Nm Fiber Laser

Lasers | Photonics Handbook®

Lasers | Photonics Handbook®

…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…

…been using polarization-maintaining fiber and saturated-absorber technologies for many years and
are approaching now lifetimes in excess
of 30.000 h for some of our fiber solutions." The company's lasers emit at 780,
1030, 1064, or 1550 nm.

Other aesthetic procedures
Laser body fat removal (lipolysis) is a
growing application for the transdermal application of light using 1060 nm
direct and fiber coupled diode lasers.
The absorption of 1060 nm light by…
