Laser Diodes & Sources

Fiber Coupled Narrow Line Laser Source

The FCNL series of Fiber Coupled Narrowline Laser Sources delivers linewidths as narrow as 3kHz and output power up to 200mW in single-mode or polarization-maintaining fiber. Each benchtop laser source features high-precision, low-noise auto-feedback drive electronics to ensure constant output power or constant driving current. An integrated temperature control unit maintains optimal operating conditions, and a built-in isolator prevents reflection-induced laser instability. Each unit includes a front fiber output connector and a universal power supply compatible with 100 to 240 VAC. We offer two package options: a benchtop version for ease of use, and a compact module for system integration. The benchtop model features an intuitive LCD display with independent controls for output power and temperature, accessible via two front rotating knobs.
