1580nm DFB Butterfly Laser Diodes Manufacturers

laser distance measurng uses a laser as a light source for ranging. According to the way the laser works, it is divided into continuous optical devices and pulse lasers. Ammonia, gas ions, atmosphere temperature and other gas detectors work in a continuous forward state, used for phase laser ranging, dual heterogeneous semiconductor lasers, used for infrared ranging, ruby, gold glass and solid-state lasers , used for pulsed laser ranging.

A laser that uses a doped fiber as a gain medium, or a laser whose laser resonator is mostly composed of fiber.

Let's take a look at which scenarios the DFB Butterfly Lasers is mainly used in.

Box Optronics launched a 1550nm, 100mW, 100kHz narrow-linewidth DFB laser diode in a 14-pin butterfly package with integrated TEC temperature control and monitoring PD.

In various optical fiber interference instruments, in order to obtain the maximum coherence efficiency, the polarization state of the optical fiber propagating light is required to be very stable. The transmission of light in a single-mode fiber is actually two orthogonal polarization fundamental modes. When the optical fiber is an ideal optical fiber, the transmitted fundamental mode is two orthogonal double degenerate states, and the actual optical fiber is drawn due to There will be unavoidable defects, which will destroy the double degenerate state and cause the polarization state of the transmitted light to change, and this effect will become more and more obvious as the length of the fiber grows. At this time, the best way is to use Polarization maintaining fiber.
