High Power Narrow Linewidth Laser
Amonics' high power narrow linewidth laser (AULLD series) integrates high power fiber amplifier with narrow linewdith laser. It features narrow linewidth, low phase noise, ultra low RIN, high output power with exceptionally reliable performance.
The turnkey microprocessor controlled benchtop AULLD provides alarms and status indicators. An integrated RS232 or Ethernet computer interface provides easy control, diagnostic functions and data acquisition.
It is particularly suitable for commercial fiber optic sensing applications, such as interferometric and Brillouin DTSS sensing systems for oil & gas, security, metrology and smart infrastructure.
