ليزرات الحالة الغازية( GAS LASERS)

الليزرات الغازية من أهم الليزرات التي تستخدم في المجالات العلمية المختلفة ، حيث نجد أن الوسط الفعال لهذه الليزرات عبارة عن غازات وأبخرة العناصر المختلفة والتي يمكن اثارتها بواسطة جهد كهربائي .

من أشهر الليزرات الغازية هي ليزر الهيليوم_نيون ويعطي شعاعا" ضوئيا" في منطقة الأحمر المرئي.وليزر ثاني أكسيد الكربون (CO2) ويصدر شعاع ليزري في منطقة الأشعة تحت الحمراء البعيدة ، ويستخدم لقطع المواد الصلبة ، وكذلك ليزر الإكسيمر الذي يصدر شعاع ليزري في منطقة الأشعة فوق البنفسجية .

تطبيقات ليزرات الحالة الغازية :

يستخدم ليزر الهيليوم_نيون بشكل رئيسي في صنع الصور المجسمة ، وكذلك في الطباعة بالليزر حيث يتم استخدام ليزر الهيليوم_نيون كمصدر للكتابة ، كما يستخدم في قراءة الرموز الشريطية المطبوعة على المنتجات في المتاجر .

يستخدم ليزر غاز النيتروجين و ليزر الإكسيمر في ضخ الليزر الصبغي النبضي .
