Description
The Venteon Pre-Amp Modules are advanced femtosecond preamplifiers designed to efficiently amplify low-energy pulses (~10 pJ) to significantly higher power levels. Operating at a center wavelength of 1030 nm, these modules are ideal for use in conjunction with the Venteon dual laser system but are also suitable as standalone amplification solutions for other laser systems.
These pre-amp modules offer flexible configurations for energy scaling and pulse picking. The Pre-Amp 1 model allows for simple pulse energy scaling, while the Pre-Amp 2 incorporates a fiber-coupled pulse picker for reducing the fundamental repetition rate of the seed oscillator. The modules feature stabilized output power, ensuring reliable performance over long-term operation, and are equipped with interlock functions for enhanced safety.
With femtosecond pulse durations, high output power, and excellent beam quality, the Venteon Pre-Amp Modules are optimal for seeding high-power stages such as ROD-type fiber amplifiers, regenerative amplifiers, and slab amplifiers, where precision and stability are critical.
