Intracavity CO2 laser Stark spectrometer with almost-free propagation.
A high performance Stark cell has been made of which the essential features are stainless steel plates, 2-mm spacing, electric fields up to 100 kV/cm, field uniformity better than 5 x 10(-5). This Stark cell has been placed at a waist created inside a CO2 laser cavity, so that the beam propagates almost freely inside the cell. Thus we get the high sensitivity of intracavity spectroscopy but we preserve the quality and the stability of extracavity spectroscopy.
