1550nm Single Frequency Narrow Linewidth Nanosecond Fiber Laser 4

This 1550 nm single-frequency narrow-linewidth nanosecond fiber laser uses a single-frequency narrow-linewidth seed source combined with a high-power gain fiber module to deliver high peak power and high energy single-frequency pulses with stable wavelength and power output. It provides ≥50 W peak power, up to 10 μJ single-pulse energy, with pulse width tunable from 20 to 1000 ns and repetition rate tunable from 1 to 200 kHz. Ideal for coherent LiDAR, distributed fiber sensing, and related applications. Available in B2 benchtop package with SMF-28 or PM1550 fiber options.

FAQ

What is the spectral linewidth of this laser?

The spectral linewidth is ≤3 kHz (narrowest) or ≤100 kHz depending on operating conditions, making it suitable for coherent detection applications.

What fiber options are available?

SM configurations use SMF-28 fiber; PM configurations use PM1550 fiber. Both come with 900 μm ferrule, 0.3 m length, and FC/APC connector or fiber collimator output.

What is the pulse energy specification?

Maximum single pulse energy is 10 μJ at 20 kHz repetition rate and 200 ns pulse width.
