Description
High-coherence, cost-effective amplification for blue and visible wavelengths
The ILA series from Santec delivers high-power, narrow-linewidth output at challenging wavelengths using advanced injection-locking technology. Designed as a compact alternative to frequency-doubled systems, ILA amplifiers provide excellent beam quality and spectral purity for precision applications.
A proprietary auto-tracking system continuously stabilises the injection lock, overcoming the traditional sensitivity of Fabry–Perot diode amplifiers to environmental drift.
High coherence and beam quality
Delivers narrow-linewidth output with beam quality superior to typical tapered amplifier systems.
Cost-effective alternative to SHG systems
Access key wavelengths without the complexity and cost of nonlinear frequency conversion.
Optimised for atomic physics transitions
Demonstrated performance at key wavelengths used in Sr, Yb, and Rydberg experiments.
