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
LaserPXIe with Power Calibration
This figure illustrates the results of the same measurements, when the lasers are integrated into the LaserPXIe 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
Don’t require PXI?
We offer the same functionality of the LaserPXIe in a compact USB/Ethernet form factor.

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.
