Nanostructuring of thin films by ns pulsed laser interference

We show that nanosecond pulsed laser interference can be used to structure surfaces on a nanoscale. With this method, we are able to create hollow structures on various thin films like Ta, Ni, Au, Cu, Co, and NiTi. We find that the structuring mechanism is related to the mechanical effect of thermal expansion upon melting. To corroborate this model, we study materials with an abnormal behavior ...

Single-frequency Pulsed Laser Oscillator and System for Laser-ultrasonics

We present a new pulsed laser oscillator and system for the optical detection of ultrasound in materials. A single-frequency laser oscillator based on a pulse pumped Nd:YAG rod inside a ring cavity is proposed. The laser delivers single-frequency pulses of 35 W power. Power of about 1 kW can be obtained when the second rod of a dual-rod pumping chamber is used as an amplifier. Performance of th...

Lunar laser ranging

Lunar laser ranging has provided many of the best tests of gravitation since the first Apollo astronauts landed on the Moon. The march to higher precision continues to this day, now entering the millimeter regime, and promising continued improvement in scientific results. This review introduces key aspects of the technique, details the motivations, observables, and results for a variety of scie...

Detecting Topological Defect Dark Matter Using Coherent Laser Ranging System

In the last few decades, optical frequency combs with high intensity, broad optical bandwidth, and directly traceable discrete wavelengths have triggered rapid developments in distance metrology. However, optical frequency combs to date have been limited to determine the absolute distance to an object (such as satellite missions). We propose a scheme for the detection of topological defect dark...

Measuring Snow Depth with a Terrestrial Laser Ranging System

Knowledge on the spatial and temporal distribution of snow depth is one of the key parameter in the assessment of avalanche hazards, for snow drift and avalanche modelling and model verification. Reliable measurements of snow depth distribution are of interest for practitioners as well as for scientists. Most of the conventional methods like snow pits, probing or profiling deliver point informa...
