IRVINE, Calif., Oct. 14, 2009 – Newport Corp. has introduced ultrabroadband dielectric mirrors and Nd:YAG laser mirrors. Both thin-film coated mirrors are designed to deliver improved performance, stability and durability for applications that require endurance in harsh environments or that need to withstand high laser pulse energy.

Newport_LaserMirrors.jpgThe ultrabroadband mirrors are coated via an ion beam-sputtering process with multiple layers of dielectric materials. They provide >99% reflection and are highly stable over a broadband wavelength range. The BB.1-coated mirror covers the UV to visible wavelengths from 350 to 700 nm and functions well in many new analytical systems where there are several diode lasers integrated that may require reflectivity over a wide spectrum of the laser light.

The BB.2-coated mirror is an economical version of the company’s superbroadband ultrafast mirror for the Ti:sapphire laser and covers the visible to near-IR wavelength spectrum from 650 to 1130 nm. It is suitable for users who are not concerned about the group velocity dispersion effect on the laser pulse. Both ultrabroadband mirrors are designed to operate within a 0 to 50° angle of incidence. The special coating is designed to withstand a higher damage threshold over a wide wavelength range, compared to normal dielectric mirrors.

The company’s new high-energy Nd:YAG laser mirrors with HE.1 and HE.2 coatings are manufactured using high-purity fused silica substrates and ultrahard ion beam-sputtered coatings. They are available with a 25.4-mm diameter for the fundamental 1064 nm and the frequency-doubled 532-nm laser lines. The combination of the ion beam-sputtered coating technique and the durable fused silica substrate material used in these mirrors permits them to withstand energy fluence as high as 40 J/cm² at 1064nm and 8 J/cm² at 532 nm.

GLOSSARY
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
