980nm pump laser diode Manufacturers

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.

The 974nm 600mW Pump Laser Diode are designed as pump sources for erbium doped fiber amplifier (EDFA) applications. Processes and techniques of coupling the fiber to the laser allow high output powers that are very stable with both time and temperature. The grating is located in the pigtail to stabilize the wavelength. Devices are available with kink free output powers to 600mW. The 976nm 600mW PM FBG Stabilized pigtailed butterfly Pump laser diode series pump module utilises a Fiber Bragg Grating design for enhanced wavelength and power stability performance. This product has been designed to ensure superior wavelength locking over drive current, temperature and optical feedback changes.

Long Wavelength 2.0μm-band 1850~2000nm ASE Broadband Light Source is based on thulium fiber laser technology and with high output power.

The 1390nm DFB 2mW Coaxial Pigtail Laser Diode have an excellent simulation performance due to the use of a DFB chip. The output power is controlled within 1 to 4 mw based on customer needs, which makes this laser module ideal for use in CATV, digital, and analog signal transmissions.

Multi Wavelength Gain Flattened EDFA Amplifier is a series of fiber amplifiers used in optical fiber communication system. It can amplify multiple wavelength signals in C-band at the same time, and keep the same gain among all wavelengths, with gain flatness ≤ 1.5dBm Which with wide spectrum, multi wavelength, flat gain, high gain and low noise.

1550nm 2mW 5mW Narrow Linewidth Coaxial Laser Diode is a coaxial package with small size, low cost laser diode, linewidth less than 500Khz, built-in TEC temperature control module, we provide single-mode and polarization-maintaining optical fiber options.
