1578nm 10mW DFB Butterfly Laser Diode Manufacturers

The main oscillator fiber amplifier (MOFA, MOPFA or fiber MOPA) is different from the main oscillator power amplifier (MOPA), which means that the power amplifier in the system is a fiber amplifier. The latter are usually high-power pumped cladding amplifiers, commonly produced using ytterbium-doped fibers.

Fiber optic gyroscope is the fiber angular velocity sensor, which is the most promising one among various fiber optic sensors. The fiber optic gyroscope, like the ring laser gyroscope, has the advantages of no mechanical moving parts, no warm-up time, insensitive acceleration, wide dynamic range, digital output, and small size. In addition, the fiber optic gyroscope also overcomes the fatal shortcomings of ring laser gyroscopes such as high cost and blocking phenomenon. Therefore, fiber optic gyroscopes are valued by many countries. Low-precision civilian fiber optic gyroscopes have been produced in small batches in Western Europe. It is estimated that in 1994, the sales of fiber optic gyroscopes in the American gyroscope market will reach 49%, and the cable gyroscope will take the second place (accounting for 35% of sales).

Fiber amplifier in a fiber optic data link, the amplification process that occurs over a very long transmission fiber.

High power ultrafast lasers are widely used because of their short pulse duration and peak power.Ultrafast lasers are used in material processing applications, medical fiber lasers, microscopy and other fields.

Thermistors are mainly used for temperature monitoring, overheating protection, etc. It is a temperature-sensitive semiconductor resistor whose resistance changes significantly with changes in temperature. It uses the heat-sensitive effect of semiconductor materials to measure and control temperature, and is widely used in various electronic devices and systems. Thermistors have the advantages of small size, fast response speed, and high measurement accuracy. Therefore, they have been widely used in temperature measurement, temperature control, overcurrent protection and other fields. Text symbols are generally represented by "RT".

Semiconductor lasers are a type of lasers that mature earlier and are developing rapidly. Because of its wide wavelength range, simple manufacture, low cost, easy mass production, and because of its small size, light weight, and long life, its variety develops quickly and its application The range is wide, and there are currently more than 300 species.
