Technical Aspects
There are many different arrangements to build a deposition chamber for PLD. The target material which is evaporated by the laser is normally found as a rotating disc attached to a support. However, it can also be sintered into a cylindrical rod with rotational motion and a translational up and down movement along its axis. This special configuration allows not only the utilization of a synchronized reactive gas pulse but also of a multicomponent target rod with which films of different multilayers can be created.
Some factors that influence the deposition rate:
- Target material
- Pulse energy of laser
- Distance from target to substrate
- Type of gas and pressure in chamber (oxygen, argon, etc.)

Famous quotes containing the words technical and/or aspects:
“Where there is the necessary technical skill to move mountains, there is no need for the faith that moves mountains.”
—Eric Hoffer (1902–1983)
“The happiest two-job marriages I saw during my research were ones in which men and women shared the housework and parenting. What couples called good communication often meant that they were good at saying thanks to one another for small aspects of taking care of the family. Making it to the school play, helping a child read, cooking dinner in good spirit, remembering the grocery list,... these were silver and gold of the marital exchange.”
—Arlie Hochschild (20th century)
