NPRO 125/126 Series

Continuous Wave Single Frequency IR Laser - NPRO 125/126 Series

The Lumentum NPRO 125/126 diode-pumped lasers produce continuous-wave (CW), single-frequency output at either 1064 nm or 1319 nm. Key features include fiber-optic or free-space output, narrow linewidth, low noise, frequency tunability, and adjustable power.

The NPRO 125/126 lasers are used for a variety of applications including fiber-optic sensing, coherent communications, remote antenna links, optical heterodyne, lidar oscillators, and passive sonar.

At the heart of each NPRO 125/126 laser is the unique Lumentum, monolithic NPRO laser cavity that delivers true single-frequency laser output. Since its initial development in 1985, NPRO technology has a record of reliability and top-level performance.

Amplitude noise for a typical NPRO 125/126 laser is <0.05 percent rms over the range from 10 Hz to 2 MHz, and less than −165 dB/Hz above 10 MHz (shot-noise limited). This performance is achieved by combining an inherently quiet laser oscillator with a noise reduction circuit, which effectively eliminates the laser’s natural relaxation oscillation.

NPRO lasers are built in a compact, OEM-friendly package with all necessary control electronics on the laser head to integrate easily with existing systems or new product platforms.
