Abstract AR
في هذا البحث تمت دراسة تأثير القوة الكابسة اللاخطية على تقاطع ليزرين عند منطقة البؤرة في بلازما لا تصادمية و غير ممغنطة.
أظهرت الدراسة أن اللاخطيتيتن اللتان تؤثران على التبئير الذاتي لحزمة الليزر داخل البلازما هما تغير كتلة الإلكترون عند السرع النسبية و تغير كثافة القوة الكابسة.
هاتين اللاخطيتين تعتمدان على قدرة آلا الليزرين و ليس كل ليزر لوحده.
تم حساب المجال الكهربائي لموجة البلازما الالكترونية و قورنت النتائج النظرية المستخلصة مع بعض النتائج التجريبية الحديثة.
Abstract EN
This paper presents the effect of relativistic and ponderomotive nonlinearity on cross-focusing of two intense laser beams in a collisionless and unmagnetized plasma.
It should be noted here that while considering the self-focusing due to relativistic electron mass variation, the electron ponderomotive density depression in the channel may also be important.
Therefore/these two nonlinearties may simultaneously affect the self-focusing process.
These nonlinearities depend not only on the intensity of one laser but also on the second laser.
Therefore, one laser beam affects the dynamics of the second beam and hence the process of cross-focusing takes place.
The electric field amplitude of the excited electron plasma wave (EPW) has been calculated.
Comparison of the theory with the recent experimental observations has also been presented.
