• Fiber-coupled output
• Proven nonplanar ring oscillator (NPRO) design
• Superior power stability
• Narrow linewidth
• Tunability
• Ease of use
• Ideal for OEM applications
Applications
• Fiber-optic sensing
• Coherent communications
• Remote antenna links
• Optical heterodyne
• Lidar oscillator
• Passive sonar
The JDSU NPRO 125/126 diode-pumped lasers produces 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 JDSU’s unique, monolithic, NPRO
laser cavity delivering true single-frequency laser output. Since its initial
development in 1985, NPRO technology has demonstrated a record of reliability
and top-level performance.
Amplitude noise for a typical NPRO 125/126 laser is <0.05% 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. All necessary control
electronics are onboard the laser head allowing for easy integration with existing
systems or new product platforms.
