1064nm DFB laser diode Manufacturers

Boxoptronics Large Mode Field Erbium-ytterbium Co-doped Fiber has a unique core low NA design, which can achieve high beam quality output without reducing the pump conversion efficiency. The high cladding NA ensures high pump coupling efficiency, and the large core diameter design ensures a large mode field area and a short fiber length, thereby greatly reducing the threshold of nonlinear effects. The optical fiber has good consistency, better suppresses 1um parasitic ASE, has high light-to-light conversion efficiency, and has good stability under high-power operation conditions.

1550nm Superluminescent Diodes SLED are optical sources with a rather wide optical bandwidth. In that they differ from both lasers, that have a very narrow spectrum, and white light sources, that exhibit a much larger spectral width. This characteristic mainly reflects itself in a low temporal coherence of the source (which is the limited capability of the emitted light wave to maintain the phase over time). SLED may however exhibit a high degree of spatial coherence, meaning that they can be efficiently coupled into single-mode optical fibers. Some applications take advantage of the low temporal coherence of SLED sources to achieve high spatial resolution in imaging techniques. The coherence length is a quantity frequently used to characterize the temporal coherence of the light source. It is related to the path difference between the two arms of an optical interferometer over which the light wave is still capable to generate an interference pattern.

1X2 Polarization Beam Combiner Splitter is designed to either combine or split linearlypolarized light. When used as a combiner, the linearly polarized input lights are combined into a single output with two orthogonal linear polarizations. When used as a splitter, an input light with two orthogonal linear polarizations is split into two outputs each with a single linear polarization. These polarization beam combiners are frequently utilized to combine the light from two pump lasers into a single fiber to increase the power input to an erbium-doped fiber amplifier or Raman amplifier.
