โœฆ Synopsis

The functioning of a carbon dioxide laser is generalized from the standard low nitrogen concentration, low temperature coolant to the high nitrogen concentration, room temperature air free convection cooling regime. The efficiencies of the two regimes are comparable. Theoretical arguments are presented to support this new regime.

Cotton plants were grown in late spring under full sunlight in glasshouses containing normal ambient partial pressure of CO2 (32 \_+ 2 Pa) and enriched partial pressure of CO2 (64 \_ 1.5 Pa) and at four levels of nitrogen nutrition. Thirty-five days after planting, the total dry weights of high CO2-
