ULTRAFAST AMPLIFIERS

Integra-HE

The Integra-HE Series of amplifiers are designed to deliver >7 mJ
pulses at 1 kHz repetition rates. The seed can be provided by an
integrated fiber oscillator or an external Ti:Sapphire oscillator (for
example, the Quantronix Ti-Light). Its platform includes integrated
pump laser(s), amplification stage(s), and a stretcher/compressor.
The amplifier system can be designed to deliver ultrashort (<40 fs),
femtosecond (80-130 fs), or picosecond (1-3 ps) output pulses.
This amplifier uses an architecture similar to the successful Integra-C
series, which includes a regenerative preamplifier and a multipass
power amplifier. This amplification scheme delivers the most stable
output in terms of pulse energy, spatial profile, and beam pointing.

FEATURES AND BENEFITS
• >7 mJ/pulse in compact amplifier
design
• Repetition rates 1-3 kHz, 3-5 kHz,
10 kHz
• 40-130 fs; 1-3 ps
• Superior beam quality & stability

This high power amplifier system is built on the same proven
engineering advancements found in the Integra and Odin series
of amplifier systems. Thermal stabilization and robust zero-drift
optical mounts result in an unsurpassed ±5° C operating range. The
whole system is built on our precision-engineered baseplates, giving
exceptional thermal stability and alignment-free operation. This
allows you to focus on your experiments and not the laser system.

1. Specification for constant output power in given repetition rate range.
2. If optimum power is needed at more than one repetition rate, additional optics may be required.
Systems can be operated at lower repetition rates through internal divide-down electronics.
3. Requires a seed source with more than 15 nm bandwidth.
4. Requires a seed source with >40 nm bandwidth.
5. Requires a >200 mW seed source with <10 nm bandwidth.
6. High contrast ratio option (>1000:1) available.
