The tuning feature allows the user to counteract temporal defects from misalignment within the compressor hardware and offset amplifier-induced nonlinear effects. Tunability also reduces the product development cycle times and compensates for manufacturing variations. The all-fiber construction creates a compact and environmentally stable package suitable for a variety of demanding applications. The result is a customizable femtosecond pulse stretcher that enables ultrafast laser systems that are powerful, low-maintenance, and cost-effective.
Early on, TeraXion recognized the emerging importance of ultrafast fiber lasers for industrial and medical applications. The TPSR is specifically designed for the generation of ultrafast pulses as short as 150 fs that are pedestal-free with high energy, average power, and low cost while remaining environmentally stable.
- Our exclusive FBG dispersion management expertise facilitates accurate phase control, which enables pedestal-free femtosecond pulses.
- Tunability virtually eliminates the need for compressor hardware temporal alignment and servicing.
- Our flexible and user-friendly software options make it easy to integrate the TPSR pulse stretcher with any laser design.
