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:
“The best work of artists in any age is the work of innocence liberated by technical knowledge. The laboratory experiments that led to the theory of pure color equipped the impressionists to paint nature as if it had only just been created.”
—Nancy Hale (b. 1908)
“An atheist may be simply one whose faith and love are concentrated on the impersonal aspects of God.”
—Simone Weil (1909–1943)
