Sphere Ultrafast Photonics is committed to finding the best solution for measuring your laser system, providing custom solutions covering different wavelength ranges, pulse durations and repetition rates
Benefiting from more than 15 years of experience, Sphere Ultrafast Photonics offers a new generation of products and services in the ultrafast pulsed laser regime
THE ULTIMATE SINGLE SHOT MEASUREMENT TOOL FOR ULTRAFAST LASER SYSTEMS
FROM OSCILLATORS TO ULTRAHIGH POWER LASER
The d-shot is a compact system for ultrafast laser pulses single shot measurement with spectrum supporting 10-50 fs and at repetition rates ranging from sub-Hz to hundreds of kHz or MHz. Coupling the laser beam into the d-shot is easily achieved in less than five minutes, and a full measurement (including retrieval) usually takes less than 10 seconds. The intuitiveness of the d-shot trace provides instant visual feedback for the optimisation of your source. This d-shot system is a practical tool for real-time alignment and optimisation of your compressor or pulse shaper, or even for measuring the pulse duration after your spectral broadening stage. A proprietary retrieval algorithm provides fast and accurate retrieval of the full electric field of the pulses.
