Summary
We developed a Yb:YAG Innoslab laser amplifier for high-energy, subpicosecond pump pulses essential for optical parametric chirped pulse amplification (OPCPA). This system achieves high repetition rates and significant average power, enabling advanced laser applications.
Area of Science:
- Laser Physics
- Nonlinear Optics
- High-Power Lasers
Background:
- Optical Parametric Chirped Pulse Amplification (OPCPA) requires high-energy, ultrashort pump pulses.
- Achieving high repetition rates and high average powers simultaneously is a key challenge in laser system development.
Purpose of the Study:
- To develop and characterize a Yb:YAG Innoslab laser amplifier system for generating subpicosecond pump pulses.
- To investigate the use of subpicosecond pulses for stable continuum generation in YAG for OPCPA seeding.
Main Methods:
- Utilized a Yb:YAG Innoslab laser amplifier architecture.
- Operated the system at high repetition rates (up to 100 kHz).
- Investigated continuum generation in a YAG crystal using subpicosecond pulses.
Main Results:
- Achieved pulse energies up to 20 mJ at 12.5 kHz.
- Attained repetition rates up to 100 kHz.
- Generated pulses with durations of 830 fs and average power exceeding 200 W.
Conclusions:
- The Yb:YAG Innoslab laser amplifier system is effective for generating high-energy, subpicosecond pump pulses for OPCPA.
- Subpicosecond pulses are suitable for deriving stable continua in YAG crystals for OPCPA seeding.
