Challenges

laser characterization and controlMeasuring the spectrum of a laser diode emission with a resolution of a few pm is necessary when addressing different kinds of issues: the use of a laser source for metrological applications based on interferometry or other physical phenomena such as the Raman effect or atom cooling usually requires pure spectra or, at the very least, good knowledge of the true spectral characteristics.
Laser users and integrators often have a huge choice of laser sources but with limited information on their laser spectrum unless they use an intrinsically pure laser, as for instance a HeNe laser. This can lead to serious difficulties in understanding the results of metrological setups or industrializing products. And here lies the need to evaluate source quality, the true operating range or component uniformity.

Measuring the spectrum of a laser with high resolution is also a necessity when developing new and innovative lasers.

Solution

Thanks to SWIFTSTM technology, our laser spectrum analyzers and wavelength meters are the ideal solution for laser analysis and control in the range of 630 to 1100 nm. They can display a laser line profile up to a spectral resolution of 3 GHz.

In addition, a high data rate measurement capability (up to 30 kHz) and several trigger mode options offer a unique configuration for testing pulsed lasers. Furthermore, their user interface includes an automatic peak detection feature and a real time visualization of the peaks stability over time.
