gem 473

The gem 473 laser system is at the cutting edge of DPSS laser technology. The innovative architecture generates up to 500 mW of blue CW power at 473 nm, making it among the highest powered blue lasers available. The gem 473 offers a low M² beam and a lower noise and stability specification, which extends its versatility. The combination of high power at this wavelength, good collimation and a compact package make this a unique product.
