We report the demonstration of a heat-fraction-limited CW Yb:YAG laser operating near 77 K with output at 1029 nm, pumped with a diffraction-limited room-temperature CW Nd:YAG laser operating at 946 nm. With a 50% reflectivity outcoupler, the average threshold absorbed pump power was 18.8 mW and the average slope efficiency 91.9%, close to the heat-fraction limited value of 91.5%. Average optic...

Laser ablation is becoming a dominant technology for direct solid sampling in analytical chemistry. Laser ablation refers to the process in which an intense burst of energy delivered by a short laser pulse is used to sample (remove a portion of) a material. The advantages of laser ablation chemical analysis include direct characterization of solids, no chemical procedures for dissolution, reduc...

We are reporting on a design, construction and performance of various solid state photon counting detector packages suitable for laser tracking of orbiting space debris. Our group has designed and constructed several solid state photon counters for application in space related projects in the last years. In all these earlier applications the timing resolution, stability and operation at 532 nm ...

We demonstrate a novel compact solid-state laser source for high-resolution two-photon spectroscopy of the 1S − 2S transition in atomic hydrogen. The source emits up to 20 mW at 243 nm and consists of a 972 nm diode laser, a tapered amplifier, and two doubling stages. The diode laser is actively stabilized to a high-finesse cavity. We compare the new source to the stable 486 nm dye laser used i...

We have developed laser-produced plasma X-ray sources using femtosecond laser pulses at lOHz repetition rate in a table-top size in order to investigate basic mechanism of X-ray emission from laser-matter interactions and its application to a X-ray microscope. In a soft X-ray region over 5 nm wavelength, laser-plasma X-ray emission from a solid target achieved an intense flux of photons of the ...

Microfluidic dye lasers (MDL) have recently emerged as promising candidates to facilitate the fusion of optics and fluidics at the microscale. Their primary advantage over gas or solid state lasers is the inherent wavelength tunabililty which can be achieved by changing the type of dye used, the dye concentration, or the host solution. Here, we report on the design and characterization of a MDL...

Knee joint is the most important joint in the human body. 3D CAD modelling is the most important part for analysis Reverse engineering is one of the process by which 3D CAD model can be easily generated. Different techniques available for generating CAD models. The paper describes the methodology applied in the development of an anatomically detailed three-dimensional knee model from 3D laser s...

LLE Review, Volume 104 208 Introduction There is much interest in both experimental and theoretical studies of laser–solid target interactions with picosecond laser beams at relativistic intensities because of their relevance to fast ignition in laser fusion1 and backlighter development.2,3 High-intensity, ultrashort laser pulses impinging onto solid or gaseous targets produce large quantities ...

The use of semiconductor diode lasers as pump sources for solid-state lasers was demonstrated as early as 1964.1 In the past few years the dramatic increase in output power of diode lasers 2 has made pumping of solid-state lasers practical. Recently it was shown that diode-laser-pumped Nd:YAG lasers offer advantages over lamp-pumped lasers, including high efficiency3 and good frequency stabilit...
