lasants for transfer blackbody-pumped lasers
Abstract
The concept of transfer blackbody-pumped lasers is outlined, recent research results concerning these lasers are presented and the search for new lasant materials for transfer blackbody-pumped lasers is expanded. There are two basic concepts for the blackbody-pumped transfer laser which are schematically drawn. The first concept is called the translational heating concept, an example being N2:CO2. Here the blackbody cavity is heated to approximately 2000 K by collected sunlight in space. An absorbing molecule would come in contact with the blackbody walls thus coming into equilibrium with the blackbody temperature. An alternative concept shown is called the vibrational heating transfer laser. Here the absorbing molecule is not translationally heated. Energy is coupled to the molecule only by optical absorption creating a high density of vibrational states. Thus the gas temperature is near room temperature whereas the vibrational temperature comes into equilibrium with the blackbody temperature.
