概要
- 論文の詳細を見る
Energy monitor in high power CO<SUB>2</SUB> laser system is required high performance, for instance, wide dynamic range and high sensitivity. Moreover, it must have large aperture size for detecting large laser beam. Pyroelectric pol-yvinylidene-fluoride (PVDF) calorimeter has sufficient properties to satisfy the needs as ment mentioned above. We have developed 350 mm<SUP>φ</SUP> pyro-film (PVDF) calorimeter of which laser absorption layer was 50μm thick Nextel paint. Its dynamic range was 3 x10<SUP>5</SUP> and high sensitivity was acquired.
