Ultrashort Laser

Abstract This paper presents the use of pulsed laser stimulation with picosecond and femtosecond laser pulses. We first discuss the resolution improvement that can be expected when using ultrashort laser pulses. Two case studies are then presented to illustrate the possibilities of the pulsed laser photoelectric stimulation in picosecond single-photon and femtosecond two-photon modes.

Thermomechanical Damage

This paper discusses high precision microscale laser bending and the thermomechanical phenomena involved. The use of a pulsed and a CW laser for microscale bending of ceramics, silicon, and stainless steel is demonstrated. For each laser, experiments are conducted to find out the relation between bending angles and laser operation parameters. Changes of the ceramics surface composition after laser irradiation are analyzed using an electron probe microanalyzer (EPMA). Results obtained by the pulsed and the CW laser are compared, and it is found that the CW laser produces more bending than the pulsed laser does. However, the pulsed laser causes much less surface composition change and thermomechanical damage to the targets. Numerical calculations based on the thermo-elasto-plastic theory are carried out and the results are used to explain the phenomena observed experimentally.

ABSTRACTThe fundamentals of energy transfer in semiconductors during and following pulsed laser excitation are reviewed within the frame of results obtained in picosecond laser experiments. This paper discusses the theoretical processes as well as the experimental evidence, which sets limits of electron and lattice temperature of irradiated silicon. Simple thermal melting is the most probable explanation for the laser induced phase transitions observed.
