            "мощности в портативном корпусе. Практическое решение лежало не в тщетных попытках увеличения ёмкости аккумуляторной "
            "батареи, а в использовании радикальных технологий миниатюризации с целью облегчения и уменьшения размеров существующих "
            "лазеров с химической накачкой. Они использовались довольно долгое время, будучи частью экспериментальных военных "
            "программ с конца XX века, но их применение всегда сталкивалось с множеством проблем. Модели химических лазеров с "
            "реальными военными перспективами были слишком большими и громоздкими для использования в бою пехотой. До сих пор их "
            "расположение было ограничено выбором между лазерными орудиями на сухопутном шасси и батареями морского базирования. "
            "Боевое применение заключалось в основном для целей противоракетной обороны (ПРО). Тем не менее, теперь мы в ФАЛАНКС "

            "описание принципа его работы. Внутри камеры сгорания этилен окисляется в пламени трифторида азота. В ходе этой реакции "
            "выделяются свободные радикалы фтора, которые затем приводятся в контакт с газообразной смесью гелия и дейтерия. Дейтерий "
            "вступает в реакцию с фтором, что приводит к образованию энергетически возбуждённых молекул фторида дейтерия. Они "
            "подвергаются стимулированной эмиссии в оптическом резонаторе оружия, генерируя лазерный луч. Серия интеллектуальных "
            "линз фокусирует и направляет луч в точку прицеливания, и даже вносит коррекцию, с учётом небольших перемещений стрелка "
            "и/или цели. Излишки газообразного дейтерия направляются через сконструированную нами систему фильтров высокого давления, "
            "которые задерживают все токсичные и радиоактивные молекулы перед выбросом отработанных паров в атмосферу. Фильтр требует "
            "замены после каждой боевой операции, но разработанная нами система делает этот процесс простым и безболезненным. Если ";
