BASIC OPERATING PERFORMANCES OF THE MINI LASER HEAD

Lasing material:                                          Gas mixture CO2/N2/He (typical)

Operating pressure:                                    Atmospheric

Wavelength:                                                10.6 micrometers

Active discharge volume:                           1cm  x  1cm  x  16cm, (i.e. 16 cm3)

Output energy per pulse:                            0.25 J (multimode operation)

Specific output energy:                               16 J/l (typical)

Pulse width:                                                 100 ns (initial spike)

Pulse power:                                                about 1 MW

Repetition rate:                                           0.5-5 Hz (typically 1Hz)

Dimension of the laser beam:                     1cm  x  1cm (multimode operation)                                                                      (6 mm - beam diameter: TEMoo mode)

Optics:                                                          Gold coated flat total reflector; 85% R/AR germanium (or                                                                       ZnSe) output coupler, 5 m radius of curvature.

Resonator length:                                         21 cm.

External dimensions of the mini head:         width-9 cm  x  height-9 cm  x  length-22.5 cm.

Weight:                                                          2.5 kg.

          Line arrangement of several mini laser heads can ensure higher active discharge volume and thus higher laser output energy than a single head one.
