b-shot
Real Time Measurement and Control of your Ultrafast Laser Amplifier
The b-shot is a compact, user-friendly system for measuring ultrafast laser pulses across a broad range of repetition rates, from single-shot to megahertz. The b-shot provides real-time, video-rate measurements, while its intuitive trace delivers immediate visual feedback, enabling rapid optimization of your laser source or experiment.
The b-shot is ideal for real-time alignment and fine-tuning of laser systems, pulse shapers, and pulse post-compressors, as well as for monitoring the temporal profile and duration of pulses after spectral broadening stages. Its proprietary retrieval algorithm enables the fast and accurate reconstruction of the full electric field, making the b-shot a powerful tool for advanced ultrafast diagnostics. Combining precision, speed, and simplicity, the b-shot makes pulse characterization easy and efficient in both laboratory and industrial environments.
