The PowerSpectrum™ TPSR-Xtended tunable pulse stretcher is a compact, robust and cost-effective solution to control pulse durations in chirped-pulse amplification (CPA) systems that use diffraction grating (Treacy) or volume Bragg grating (VBG) compressors. The TPSR-Xtended is specially designed for high-energy lasers which require more stretching of the pulse before the amplification chain. The tuning feature allows the user to control the duration of the pulse and offsets amplifier-induced nonlinear effects. Tunability also reduces the laser system 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 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-Xtended is specifically designed for the generation of ultrafast pulses below 150 fs that are pedestal-free with high-energy, high average power, and low-cost while remaining environmentally stable.

  • Our exclusive FBG dispersion management expertise facilitates accurate phase matching, which enables pedestal-free femtosecond pulses.
  • Our in-house pairing of each TPSR-Xtended to a specific customer-provided volume Bragg grating (VBG) or diffraction grating (Treacy) compressor minimizes phase errors for optimal pulse compressibility.
  • Our flexible and user-friendly software make it easy to integrate the TPSR-Xtended pulse stretcher with any laser design.

Top 5 Features

Accurate

The TPSR-Xtended will accurately fine tune the phase, thus allowing for a dynamic pulse control to reach the highest peak-power.

Versatile

The lastest tunable pulse stretcher maximizes performance at any energy regime and for every laser produced. 

 

Low Cost

The ingenious, all-fiber design of the TPSR-Xtended is the most cost-effective way to temporally shape the pulse in comparison to electro-optic or MEMS-based pulse shapers. 

Reliable

The TPSR-Xtended is based on the technology of our Telcordia®-qualified telecom products which are still operating after decades of use.

Customizable

Compatible with almost any laser architecture comprising different types of amplifiers and compressors.
