- The design of solid state pulsed power modules for excimer lasers have been long-established over many years.
- Pulsed laser deposition (PLD) of organic and biological thin films has been extensively studied due to its importance in medical applications among others.
- Having established acceptance for themselves as machine tools in drilling, cutting and welding operations, lasers are now winning recognition as thermal sources for the surface treatment of metallic engineering components.
- Pulsed Laser Ablation in Liquid (PLAL) has become an increasingly important technique for metals production and metal oxides nanoparticles (NPs) and others.

- Of all laser-based processes, laser machining has received little attention compared with others such as cutting, welding, heat treatment and cleaning.
- Laser energy attenuation greatly influences the amount and distribution of laser energy, which affects the forming precision and quality in laser solid forming.
- Today`s new generation lasers require durable beam dumps which can absorb large amounts of energy remaining structurally sound.
- Investigations in fs-laser damage mechanisms have proven that the interaction of ultra-short laser pulses with dielectric matter is driven by electronic processes.This fact leads to a deterministic damage behavior and a well defined dependency of the laser-induced damage threshold (LIDT) on the absorption gap of the dielectric optical material which should allow better calculation of likely damage.
- With the increasing number of laser applications in medicine and technology, accidental as well as intentional exposure of the human eye to laser sources has become a major concern.
- Reflection high energy electron diffraction (RHEED) has become ubiquitous in growth chambers worldwide, and has been used since the 1980s for in-situ characterization of thin films grown by both molecular beam epitaxy as well as pulsed laser deposition (PLD).
- For high repetition operation of excimer-lasers care has to be taken of the changing performance of the electrical circuit, gas dynamic effects and contamination of the gas mixture to avoid deterioration of the laser performance.
- Phenomena of nonlinear light-matter interaction that occur during the propagation of intense ultrashort laser pulses in continuous media have been extensively studied in ultrafast optical science.
- High-pressure arcs which operate in LTE or near LTE have important commercial applications for switchgear, plasma torches, plasma chemistry and analysis, lighting etc.
- The interaction of laser beams with solids has played an important role in many disciplines, such as laser processing of solids, laser-induced mass spectrometry and film deposition by pulsed lasers.
- the range of intensity 1013-1014 W/cm2, material processing with ultrashort laser pulses is characterized by the absence of a plasma shielding effect and a small heat affected zone.
