Narrow Linewidth 1550nm 1560nm Picosecond Pulsed Fiber Laser

1550nm narrow linewidth tunable picosecond Pulsed Fiber Laser is an all-fiber polarization maintaining mode-locked fiber laser, based on semiconductor saturation absorption mirror. The pulsed laser provides an effective management interface for user to control the key operating parameters. It presents RS-232 interface flexibly, ensuring the connectivity with customers control system. It is controlled by automatic power control mode (APC mode) with narrow pulsewidth, narrow spectral linewidth and stable output power. The center wavelength can be fastly tuned by temperature. Refer to the typical test results (Spectrum and Auto correlation curve) as following . Please contact us for the price before placing the order.

A narrow-linewidth laser with excellent temporal coherence is an important light source for microphysics, space detection, and high-precision measurement. An ultranarrow-linewidth output with a linewidth as narrow as subhertz has been generated with a theoretical coherence length over millions of kilometers.

Continuous lasers.

The laser linewidth in a typical single-transverse-mode He Ne laser (at a wavelength of 632.8 nm), in the absence of intracavity line narrowing optics, can be on the order of 1 GHz.
