Abstract

To promote the engineering applications of high power TEA CO

lasers

the miniaturization and lightweight of the host structure was studied. A new type of host structure with annular flow channel replaced the original cylindrical structure. The way of finite element analysis was used to simulate the stress and deformation of the shell structure. Through the comparison between the two structures on the stiffness

stability and weight

the cassette shell with the ribs which reduced the thickness of shell from 7 mm to 4 mm replaced the shell without ribs. The maximum deformation was reduced nearly an order of magnitude which was from 1.11 mm to 0.126 mm. The developed shell's maximum error between measured deformation and the simulation results was only 1.58%.After measurement

comparing with the cylindrical host

the volume of the new annular flow channel host was reduced by 30% and the weight reduced by 40%. The airflow rate in the discharge zone increased from 84.8 m/s to 97 m/s. After the test of the optic under the same operating para-meters

it is showed that the repetition frequency of the new laser is improved from 400 Hz to 470 Hz and the average output power is improved from 6 800 W to 7 900 W.
