Özet:

 High harmonic generation HHG in pure nitrogen N2 and its mixture with neon Ne gas was produced. The external laser field producing 6mJ optical pulse energy with 50fs pulse duration at 10Hz repetition rate was focused into a gas jet producing high harmonics. The N2 and Ne gas have different ionization potentials. The strong harmonic signal in pure N2 was produced, and a weak harmonic signal in a mixture of N2-Ne was generated compared to that in pure N2. The increase of Ne contribution in the N2-Ne mixture resulted in a decrease in harmonic signal. Harmonic signal increase and decrease were observed for different N2:Ne ratios. The harmonic generation mechanism was discussed in that the ionization of Ne is difficult compared to N2, and the neutral Ne atom leads to neutral atomic dispersion phase mismatch, so the harmonic yield decreases.

 Saf nitrojen N2 gazından ve bunun neon Ne gazı ile karışımından yüksek harmonik mertebeler HHG üretildi. 10Hz tekrarlama hızında 50fs optik darbe süresi ile 6mJ optik darbe enerjisi üreten lazer alanı, yüksek harmoniklerin üretildiği bir gaz jetine odaklandı. N2 ve Ne gazı farklı iyonlaşma potansiyellerine sahip olduğu için saf N2 gazında güçlü harmonik sinyali ve saf N2ye kıyasla N2-Ne karışımında zayıf harmonik sinyali elde edildi. N2-Ne karışımında Ne katkısının artması harmonik sinyalin zayıflamasına neden oldu. Farklı N2:Ne oranı için harmonik sinyal artışı ve düşüşü gözlendi. Harmonik üretimi mekanizması, Ne iyonlaşmasının N2ye kıyasla zor olduğu tartışıldı, ve nötr Ne atomunun, nötr atomik dispersiyona yol açtığı faz uyumsuzluğu ve böylece harmonik sinyalin azalmasına neden olduğu açıklanmıştır.
