HY-NLL Ultranarrow-Linewidth Laser
The HY-NLL ultranarrow-linewidth laser series uses an InGaAsP/InP quantum-well gain chip and proprietary external-cavity structure. An integrated isolator and TEC cooling provide stable single-frequency, polarization-maintaining output. Linewidth options include≤3kHz,≤5kHz,≤10kHz, and≤20kHz, with side-mode suppression exceeding55dB. A stable structure and mature volume-manufacturing process are combined with14-pin butterfly packaging. Output is insensitive to vibration and temperature changes, suiting demanding environments.
