There are lots of information regarding output power, tuning range, infrared, calibration, noise ratio, and signal are presented inside this paper. Below are taken from this paper:

Introduction In recent years there has been an increasing interest in detection and precise measurement of environmentally important atmospheric trace gases such as nitric oxide NO , carbon monoxide CO , nitrous oxide N2O , formaldehyde H2CO , methane CH4 , and sulfur dioxide SO2 . At any point in the scan, the Beer–Lambert law for the power transmitted in the presence of CO, P , as compared with the power transmitted in the absence of CO, P0 , is P P0 exp CL , where is the absorptivity, C is the concentration of CO, and L is the path length of the cell.

Even more, this paper contains info around detector, absorption signal, frequency, wavelength, and infrared transitions.
