Pulse Diagnostics

APE offers a choice of solutions for ultrafast pulse measurements. Each is tailored to your type of laser system, with a wealth of innovations for greater accuracy and user simplicity.


Via the waveScan technology, A·P·E offers a spectrum analyzer for different wavelength ranges of CW and mode-locked laser systems. Featuring high resolution and supreme ease of use, several versions of waveScan are available, to allow measurement of scan rages ranging from 200 ... 6300 nm.


High Resolution Optical Spectrum Analyzer

waveScan by APE is a compact and cost-efficient optical spectrum analyzer for ultrafast laser systems, delivering rapid measurements at high resolutions. The rotating grating technology achieves high scan rates, making it an ideal real-time alignment tool for mode-locked laser systems. Different configurations, from 200 nm UV to 6.3 µm in the mid-infrared range, make waveScan the choice for analyzing the spectrum of different laser types. As an option, waveScan is available with an interchangeable fiber input in addition to a free-space input. Whether you need fast scan rates for adjustment or high resolution, combined with convenient measurement control and data processing - waveScan is the ideal solution.
