Following the development of the arc lamp pumped Nd:LMA laser [17,18], further development of this approach was pursued at the University of Mainz in the early 1990's .
Metastable atoms are produced by a weak electrodeless radio-frequency (if) discharge, and optically pumped by light at a wavelength of 1083 nm.
The metastable atoms are optically pumped by 1083 nm wavelength light that is produced by a Nd:LMA (neodymium-doped lanthanum magnesium hexaluminate) laser.
In addition we optically pumped to the lower energy state.
Although higher power than we have obtained has been reported for arc-lamp pumped Nd:LMA lasers , we have found that the attainable performance is variable and seems to be linked to the quality of each laser rod.

Echocardiography also can be used to calculate a patient's ejection fraction, a measure of the amount of blood pumped out when the heart contracts.
As a result, the heart beats less frequently but more effectively, and more blood is pumped into the arteries.
