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.

1550nm Single Frequency Narrow Linewidth

Name: 1550nm Single Frequency Narrow Linewidth Nanosecond Fiber Laser

SKU: NL-NSFL-1550-20/1000-50-1/200-SM-B · 1550 nm
Availability: InStock

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.
