PWS – TPSR-V Tunable Pulse Stretcher for Ultrafast Laser with VBG Compressor

Tunable Pulse Stretcher for Ultrafast Laser with VBG Compressor

TPSR for web

The PowerSpectrum™ — Tunable Pulse Stretcher is a compact, robust and cost-effective solution to control pulse durations in ultrafast laser systems using a volume Bragg grating (VBG) compressor.

It guarantees optimal peak power and dynamic and precise pulse control in any circumstance. It improves laser performance by compensating the group delay error of volume Bragg grating (VBG) compressors, and contributes to forming the smallest stretcher-compressor pair in the industry.

Each PowerSpectrum™ — TPSR-V is paired in-house to a specific volume Bragg grating (VBG) compressor, greatly improving the robustness of the laser and through simpler and fewer bulk optics alignments at the compression stage. Its flexible software options make it easy to integrate within any design and allow for a fully electronic calibration of lasers systems, resulting in shorter cycle times, increased throughput and lower operating costs.
