ملخص المقالة :
همجوشی هسته ای هلیوم-3 (He3) ممکن است با استفاده از پالس های لیزری پتاوات-پیکوثانیه برای انفجار جانبی همجوشی پروتون-بور (HB11) بدون نیاز به فشرده سازی، امکان پذیر باشد. همجوشی HB11 برای تولید همان میزان انرژی، تشعشع بسیار کمتری نسبت به نیروگاه های زغال سنگی ایجاد می کند. این روش به تکنیک احتراق جانبی چو-بوبین (Chu-Bobin) وابسته است که برای جلوگیری از پدیده ای به نام خود کانونی شدن نسبیتی (relativistic self-focusing)، پیش پالس ها را کاهش می دهد. پیش بینی های تئوری برای بلوک های پلاسمای بسیار جهت دار با دماهای متوسط و چگالی جریان یونی فوق العاده بالا (بالغ بر 10^11 آمپر بر سانتی متر مربع) با آزمایش ها تأیید شد. شتاب توسط نیروی غیرخطی ایجاد شد. این نتایج، درِ همجوشی چگالی جامد با احتراق جانبی چو-بوبین را باز می کند. در نهایت، مقایسه ای دقیق بین احتراق جانبی و فشرده سازی استاندارد لیزری کروی شکل برای تأکید بر تمایزهای اساسی در فرآیند احتراق نشان داده شده است.
