The wear resistance of high-value copper components used in the metal casting, automotive, aerospace and electrical equipment industries can be improved by applying nickel (Ni)-based coatings through laser cladding. A high-power diode laser array pro

A significant enhancement in the rate of material removal is demonstrated using a nanosecond-pulsed UV fiber laser in multi-pulsing burst mode, as compared to the case without bursting. Percussion drilling and scribing of thin-film and bulk material

A laser-based technique for monitoring temperature in shock tube flows is reported. The method employs a rapid-tuning ring-dye laser to record the fully resolved absorption spectrum of the R(1)(7) and R(1)(11) lines of OH near 306.5 nm. The temperatu

This letter describes a ring dye laser system and its initial application to fully resolved absorption line shape measurements of the OH molecule during the brief test time available following shock waves generated in a shock tube. The operating wave

We report on the development and testing of a laser system that delivers up to 200 mW of continuous-wave radiation at 198.54 nm in a near diffraction-limited beam, to be used as a source for photolithography mask writing and mask inspection. The sour

As the demand for semiconductor devices based upon ever-thinner silicon substrates continues to increase, mechanical techniques suitable for dicing wafers appear to be approaching their practical limits. Recent advances in power scaling have now enab

Absorption lineshapes of OH found in hot post-flame gases were measured using a rapid-tuning single-mode laser. Collisional linewidths due to broadening by H 2 O and CO 2 were determined by fitting the observed lineshapes to standardized Voigt profil
