Ultra-Low Noise, 80 W Laser System at 532 nm: Enabling Titanium-Sapphire Pumping and Advanced Semiconductor Inspection with Superior Noise Performance

The demand for high-power, low-noise laser systems at 532 nm continues to grow, driven by applications in advanced research and industry. Titanium-sapphire laser pumping and cutting-edge semiconductor inspection systems require precise and stable light sources. Currently available systems (DPSS or fiber-amplified lasers) often struggle to achieve the necessary balance between high-power performance and low noise. With acceptable noise levels, they can only reach power levels in the 20 - 30 W range, and at higher power levels, the required noise performance cannot be achieved. Our contribution details design and performance of a 532 nm laser system optimized for such applications, leveraging innovative technologies to achieve an unprecedented combination of 80 W output power and low-noise performance with an integrated RIN RMS < 0.02%.
