Footnotes:

  1. Due to our continuous product improvement program, specifications are subject to change without notice.
  2. TOPAS Prime energies scaled linearly with input energy. Energy above generated at 1 mJ input energy.
  3. 3. 5 mJ input energy requires TOPAS Prime Plus configuration.
  4. For pulse widths >150 fs, contact Spectra-Physics.
  5. Optional fresh pump available.

Features

Improved Optical Design

TOPAS Prime utilizes several key features to maximize utility and efficiency. In the visible range, the fresh pump option provides improved beam quality for more efficient sum-frequency conversion. The improved optical design accommodates a larger beam diameter, (~11 mm) which eliminates the need for an external telescope. When higher energy output is needed, the TOPAS Prime Plus can accept input energies up to 5 mJ.

Pump with Solstice Ace and Spitfire Ace Regenerative Amplifiers

The TOPAS Prime works best when pumped using the market leading Solstice Ace and Spitfire Ace regenerative amplifiers. Both amplifiers are equipped with the Spectra-Physics patented Ace regenerative amplifier cavity. This cavity utilizes a normal incidence rod design for an outstanding beam quality with minimal astigmatism. In addition, the Solstice Ace and Spitfire Ace provide market leading stability specifications making TOPAS Prime the perfect tool for performing ultrafast research.
