81663A DFB Laser, 8165xA Fabry-Perot Laser

Introduction

The Keysight 81663A high power DFB laser source modules provide stable narrow-linewidth output at key selected wavelengths.

The Keysight 8165xA Fabry-Perot Laser Sources are available as single or dual wavelength sources, are insensitive to back reflections, and are stabilized for short and long term applications.

The DFB and FP Laser Source modules are part of the flexible Keysight Lightwave Solution platform and have a futureproof design that allows for easy firmware upgrades.

Technical Specifications

Fabry-Perot source module specifications (high-power modules, +13 dBm)

Specifications describe the instrument's warranted performance. They are verified at the end of a 2-meter-long patchcord and are valid after warm-up and for an attenuation setting of 0.0 dB. All modules are equipped with straight output connectors.

Supplementary Performance Specifications

Internal digital modulation mode

270 Hz, 330 Hz, 1 kHz, 2 kHz and free selection 200 Hz to 10 kHz. All output signals are pulse shaped, duty cycle 50%.

Internal coherence control for linewidth broadening.

Output attenuation

The output power of all source modules can be attenuated from 0 dB to 6 dB in steps of 0.1 dB.

Laser safety information

All laser sources listed above are classified as Class 1M according to IEC 60825-1 (2007). All laser sources comply with 21 CFR 1040.10 except for deviations pursuant to Laser Notice No. 50, dated 2007-June-24.
