PZT FM ultra narrow-wire lasers are external cavity feedback using high Q quality factors; ultra low phase noise is achieved by self-injecting locking; and ultra narrow line wide laser output; encapsulation sizes are small; power consumption is lower; environmental disturbance resistance is better; it is widely applied to fibre-optic sensors; dry communications; compact laser radar; quantum technology, etc. Very narrow line width; very low to 1Hz resistant to environmental interference Very low long-term frequency drift Low phase intensity (RIN) noise Stabilization of single-frequency work Non-jumping Small size low power PZT band bandwidth up to 100 kHz wavelengths (1 μm, C-band; L-band)

Central wavelength: typ: 1550 2nm Width: typ: ≤ 300kHz

The laser uses the MOPA technology system; takes full advantage of the technological advantages of fibre-optic laser noise suppression and pre-magnification; obtains a high power output while maintaining the maximum beam mass, the high oscillation distillation ratio, the high optical noise ratio; and is the ideal light source for successive Doppler laser wind radars. Typical applications are on-board wind radars, short-range dry wind radars.
