A team of researchers and engineers at TOPTICA Photonics AG has achieved a breakthrough, building an ultra-low noise, high-power 532nm laser demonstrator.
Utilizing readily available building blocks from TOPTICA's product portfolio, the system delivers an impressive 80 W of optical output at 532 nm while simultaneously holding the relative intensity noise (RIN) to an exceptional level below 0.02% rms (10 Hz to 10 MHz).
The innovative combination of the narrow-linewidth external-cavity diode laser DL pro with a high-performance fiber amplifier ALS-1064-130 and the proven resonant frequency-doubling stage SHG pro significantly outperforms other, currently available DPSS or fiber-amplified based laser systems, which struggle to achieve the required combination of both high power and ultra-low noise.
The demonstrated performance enables technology advancements and higher throughput in areas such as titanium-sapphire laser pumping, leading-edge semiconductor inspection, and large-area holography.
