LaserPXIe – Modular Laser Source

The LaserPXIe-1000 is a Continuous Wave (CW), tunable laser source offering high-power output, narrow 100kHz linewidth and 0.01pm resolution tunability.

With seamless PXI integration, LaserPXIe can be easily integrated into new or existing PXI test setups. Save space, lower your costs and improve testing efficiency while delivering reliable and repeatable results in production or research environments.


  • 2 or 4 lasers per blade
  • Full tunability across C or L band
  • Smarter calibration for enhanced power flatness
  • 0.01pm tuning resolution
  • Narrow 100kHz linewidth, up to 15dBm of power
  • Seamless integration with PXIe chassis and optical and electrical modules

Target applications

  • Stable local oscillator for coherent receivers
  • WDM network loading
  • General purpose stable light source for telecom and physics
  • Amplifier testing
  • With its polarization maintaining output, it’s ideal for experiment and testing that require precise control of your polarization state.

Typical ITLA Lasers


This figure illustrates the typical output power accuracy of standard ITLA lasers. The output power of each is recorded using a NIST traceable optical power meter. Measurements from each laser are taken at 10 different wavelengths for 7 different power settings. The data is taken from random sample of 12 lasers.

Mean error (abs) = 0.25dB
Pk-Pk error = 1.038dB

LaserBlade with Power Calibration


This figure illustrates the results of the same measurements, when the lasers are integrated into the LaserBlade and controlled via the TIM application. The output power is now within 0.2dB across the entire range.

Mean error (abs) = 0.03dB
Pk-Pk error = 0.20dB

Application Notes

Measuring Laser Linewidth
Low linewidth lasers are important for use in systems such as coherent communications, fiber optic sensors, interferometric sensing and gas detection. This application note covers the theory and importance of laser linewidth measurements, especially as they relate to low-linewidth lasers.

Relative Intensity Noise (RIN) Measurement
Semiconductor laser Relative Intensity Noise (RIN) is an important parameter that can cause significant degradation to the performance of fibre optic communications links. It is important for both laser manufacturers and systems designers to understand how RIN is measured to ensure reliable, accurate and repeatable results.
