SLPR Series Non-Planar Ring Oscillator (NPRO) Lasers employ a monolithic laser
SLPR Series Non-Planar Ring Oscillator (NPRO) Lasers employ a monolithic laser crystal combined with a magnetic field to create a unidirectional non-planar ring cavity, delivering kHz-class ultra-narrow linewidth, low noise, and high frequency stability continuous single-frequency output. Robust packaging, extensive burn-in testing, and real-world integration verification ensure outstanding stability and performance.
A typical non-planar ring oscillator (NPRO) laser features a spectral linewidth < 5 kHz and relative intensity noise < -140 dB/Hz at 10 MHz, thanks to its internally stabilized oscillator and matching low-noise circuitry that effectively suppress self-relaxation oscillations.
