Neodymium Doped Laser Fiber

The advent of the fiber laser has demanded the greatest change in our perception of the laser since the invention of semiconductor devices. Fiber lasers are compact and, in some cases, may be spliced directly onto conventional optical fibers with minimum insertion loss. Their Q-switched performance makes them ideally suited to high-resolution OTDR for fault location in telecommunications links or distributed sensors. In addition, some designs display the low temporal coherence and excellent temperature stability required for a number of fiberoptic sensors, including the gyroscope.

Fibercore Limited DF1000 is the ideal introduction to fiber laser technology – neodymium doped fiber offering a very low lasing threshold, even when pumped with low-cost ‘Compact Disk’ type laser diodes. Output wavelength depends on configuration, but is typically in the region of 1064 nm to 1088 nm.
