Terahertz imaging of composite materials in reflection and transmission mode with a time-domain spectroscopy system
(2016)
A fiber-coupled Terahertz time domain spectroscopy (THz-TDS) system based on photoconductive antennas, pumped by a 100-fs fiber laser, has been used to characterize materials in transmission and reflection mode. THz images ...
Optical limiting properties of carbon disulfide at 2.05μm wavelength
(2016)
Several types of infrared sensors are based on sensitive focal plane arrays. In such sensors, the intensity will typically increase by a factor ~107 at the focal plane, compared to the intensity of the incoming radiation. ...
High-pulse-energy mid-infrared fractional-image-rotation-enhancement ZnGeP2 optical parametric oscillator
(2016)
A high-energy mid-infrared ZnGeP 2 (ZGP) optical parametric oscillator (OPO) based on the nonplanar fractional-image-rotation enhancement resonator pumped by a 2.05 μm Ho 3+ :YLF laser is presented. Up to 120 mJ pulse ...
Optical limiting properties and z-scan measurements of carbon disulfide at 2.05 μm wavelength
(2016)
Nonlinear and optical limiting properties of carbon disulfide (CS 2 ) are characterized at 2.05 μm wavelength using a 𝑄 -switched Ho:YLF laser with high pulse energy. The nonlinear refractive index of CS 2 is measured ...
