The JDSU NPRO 142 series is a compact, low-noise, 532 nm, CW laser for use in
applications including interferometry, holography, printing, detection, and
inspection. Each NPRO 142 features superior power and pointing stability, with a
round, nearly diffraction-limited beam all in a compact package. All control
electronics are contained within a small laser head in this OEM design. Only a
basic DC power source is required to drive the laser.
At the heart of each NPRO 142 laser is JDS Uniphase’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.
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.
