Product information "BG-NL Ultra-narrow Linewidth Laser"
1550 nm; Output Power ≤17 dBm; RL ≥55 dB; Output Isolation ≥40 dB; SMSR ≥55 dB; Fiber Type SM
Beogold Technology's BG-NL 1550 nm ultra-narrow linewidth laser is a proprietary low-noise fiber laser source. The uniquely designed ultra-narrow fiber filter ensures single frequency operation of the laser.
Its unique temperature control and anti-vibration design eliminates the impact of changing external temperature and vibration, thus achieving a stable longitudinal single mode (SM) and single frequency output.
The laser offers excellent performance featuring kHz-level linewidth, low frequency noise and intensity noise and a SMSR of more than 50 dB. In addition, the uniquely designed high-strength package ensures that the fiber laser module can better adapt to changing environmental conditions, such as temperature, vibration and impact, achieving longitudinal single mode operation free of mode-hops.
Beogold Technology's BG-NL single-frequency ultra-narrow linewidth fiber laser source delivers output power up to 50 mW and higher.
