AURORA-H
Ultra-Short Pulse OPA
- Optimal Combination of Collinear and Non-Collinear OPA
- Ultrashort Pulses in the Near-Infrared Spectrum (650-900 nm and 1200-2500 nm)
- Pulse duration <100 fs
- Single-shot to 1 MHz repetition rate
AURORA-H is a hybrid optical parametric amplifier (OPA) that combines the short pulse duration generated by the non-collinear optical parametric amplifier (NOPA) with the wide tunability offered by the collinear OPA. This provides it with unique performance advantages, allowing its signal light to be tuned within the range of 650-900nm, while the idler light can be tuned within 1200-2500nm. Additionally, it can perform dispersion compensation to compress pulses to a duration of 50-100 fs.
AURORA-H is compatible with various market-standard fiber and solid Yb ultrafast lasers and supports one-click precise tuning, allowing customers to easily obtain the desired central wavelength output without complex manual adjustments. This not only greatly facilitates customers but also improves operational efficiency.
Carrier-Envelope Phase Stabilization
Achieving repeatable alignment between the pulse envelope and the peak of the carrier electric field is the cornerstone of attosecond science for exploring electron dynamics.
CARS and SRS Microscopy
A nonlinear vibrational imaging technique that uses a pump–Stokes–probe four-wave mixing process to generate a resonant anti-Stokes signal, enabling label-free chemical mapping with high speed and intrinsic vibrational contrast.
