Narrow linewidth fiber laser Detailed Specifications.pdf

This document contains technical specifications for a narrow-linewidth fiber laser procurement requiring a quantity of 2 units. The laser must be tunable across a range including both 1071.18 nm and 1071.36 nm wavelengths with output power exceeding 20 mW and an output spectral linewidth of less than 3 kHz. The device shall operate as a single frequency laser with both thermal and piezo tuning capabilities, where thermal tuning covers the specified wavelength range and piezo tuning provides a minimum 100 MHz range with modulation speeds exceeding 20 kHz.

The laser shall include a PM fiber-coupled output with FC/APC connector, polarization extinction ratio of at least 20 dB, and an internal output isolator. All necessary control electronics and software for operation must be included. Performance requirements include relative intensity noise at 1 MHz of ≤ -110 dB/Hz, signal-to-noise ASE ratio of 65 dB or greater at 50 pm bandwidth, side mode suppression ratio exceeding 50 dB, and power stability below 1 percent RMS over 8 hours or longer. The laser will be installed in a temperature-controlled laboratory environment with thermal variance below 0.5°C. Output power beyond 20 mW is requested on a best-effort basis.
