Aluminum-coated hollow fibers for UV and VUV light sources
Aluminum thin film is deposted on the inside of glass tubing by MOCVD technique. The fibers shows high transmission efficiency in UV and VUV region dur to high reflectance of aluminum.
Target lasers include XeCl, KrF, ArF, and F2 excimer lasers, and other coherent and incoherent light sources.
Hollow fibers for short pulse lasers
Hollow optical fibers specially designed for Q-switched YAG lasers are available. The fibers transmits high-peak-power, nanosecond pulses of YAG and its harmonics (2nd, 3rd, and 4th).
Hollow fiberoptics also deliver femto-second pulses with high pulse energy with little pulse broadening.
Hollow glass fibers for infrared lasers
Hollow fiber for IR region of 2-12um wavelength. It is a best solution for the delivery of CO2, ErYAG laser etc.
Hollow fiber for visible/NIR/IR spectroscopy
Hollow fiber for visible/NIR/IR spectrosocopy has broad band wavelength region delivery characteristics such as 350-700nm, 0.7-2um, and 2-15um.
