Laser micro-machining of small objects for high-energy laser experiments

SiO2 Aerogels

“…For example, chemical modifications by grafting in solution after re-impregnation [96] or in a gaseous atmosphere [97], skeleton coating by chemical vapor infiltration [98], impregnation of the bulk porosity with reactive species (Figure 2.11), embedding in polymers (Figure 2.12), mechanical engineering by milling, cutting, laser micromachining [100], and thermal processing such as sintering [101] can be performed to target specific applications.…”

Experimental study of Nd:YAG laser beam machining—An overview

“…Also, the experiment was done to fabricate such metallic stent with fine structure (slit width 0.05-0.1 mm) and it was found that low laser beam heat input can reduce the HAZ substantially but dross removal requires soft etching or pickling (Kathuria, 2005). Picosecond Q-switched Nd:YAG laser was used for micromachining of different micro-parts (Bednarczyk et al, 1999). The experimental investigation shows that 800 m diameter discs can be cut successfully in a 4 m thick plate of titanium with a repeatability and accuracy of 2 m. Also, square of 2 mm and 400 m sizes were cut in 7 m and 25 m thick foils of gold and copper respectively with same accuracy as above (Bednarczyk et al, 1999).…”

PET polymer ablation using excimer laser for nozzle plate application

“…[2][3][4][5][6] Most of the results reported on only single microhole drilling processes with diameters between 10 and 100 mm. Microarray machining was not attempted in these previous works.…”
