CO2 laser Edinburgh Instruments
9.1 - 10.9 µm

The laser heads utilise an invar rod frame to support the laser resonator and ensure a high degree of passive stability. The lasers have manually controlled diffraction gratings for line selection and piezo mounted output couplers for fine control of cavity length. All laser tubes are water-cooled. The inner walls of the laser tubes are specially profiled to suppress off axis oscillations and to ensure that the lowest order mode transverse mode dominates. The low gas pressure and hence narrow gain profile supports only single longitudinal mode (SLM) operation. Polarised output. Excellent passive stability of amplitude and frequency exists. Active stabilisation is available as optional.
