The energy measurement of forth harmonic generation ultraviolet laser is an important basic part of these physical processes. This paper mainly studied the laser energy measurement, carried out the following research work on the key issues: 1. The normal laser energy measurement theories and major domestic and foreign short wavelength laser energy measurement research states are investigated to introduce the research significance. 2. Theoretical simulation is done to study the process of forth harmonic generation ultraviolet laser, and physical models of the forth harmonic generation ultraviolet laser -matter interactions are introduced. 3. A measurement of optothermal method with SiC as absorber is put forward. A Heavy caliber optothermal power meter used 6H-SiC is designed for the property measurements experiment with the forth harmonic generation ultraviolet laser as the calibration source. The performance parameters of the power meter are determined and the improvement of the experiment and the structure of the power meter are discussed . 4. A measurement of photoelectric method with ferroelectric films as energy probe material is put forward. Theoretical simulation is done to study the laser induced thermal voltage of ferroelectric films, and the feasibility of forth harmonic generation ultraviolet laser energy measurement is analyzed. 5. A measurement method with CsI:TI and CCD using the fluorescent effect of scintillation crystal is put forward. The property measurements principle diagram is designed and the feasibility of this measurement method is analyzed.
