Newport Corporation unveiled its new line of high-energy Nd:YAG laser
50/50 beamsplitters. The company now offers 16 different versions at
four center wavelengths of 266, 355, 532 and 1064 nm, in both one and
two inch diameters.
High-Energy Nd:YAG Laser 50/50 BeamsplittersAccording to Keshav Kumar,
Product Manager for Optics at Newport, “The High Energy Nd:YAG
Laser 50/50 Beamsplitters were designed to be used with
Spectra-Physics® Quanta-Ray® lasers. However, with a damage
threshold of 20.0 J/cm2 with 10ns pulse at 1064nm or 2000 MW/cm2 CW,
and 12.0 J/cm2 with 10ns pulse at 532nm or 1200 MW/cm2 CW, we believe
that these new optics are the ideal choice for any research
applications that use Nd:YAG or Nd:YLF lasers.”
Newport’s newest beamsplitters are manufactured using high purity
fused silica substrates, and ultra-hard dielectric coatings. These
beamsplitters have been specially designed to withstand high-energy
pulses and have a high damage threshold. The front of the beamsplitter
is coated with a high power beam splitting coating optimized for 45 deg
angle of incidence for S- and P- polarizations. The back surface is
coated with a high damage threshold antireflection coating. Offered in
25.4 mm (1”) or 50.8 mm (2”) diameters, these beamsplitters
offer excellent performance for scientific and industrial applications.
Kumar added, “These new 50/50 beamsplitters are an excellent
addition to our family of high-energy laser optics. Today, Newport is
one of the few companies that offers a full range of solutions for
Nd:YAG lasers including mirrors, harmonic beamsplitters, thin film
polarizers, and polarizing cube beamsplitters. In addition, we can also
provide a wide range of other high-energy solutions such as laser
wedged windows, excimer laser mirrors, laser beam expanders and
variable attenuators."
