چکیده

چگونگی توزیع عرضی شدت باریکه لیزر یا نمایه مدی از مهم‌ترین شاخصه‌های یک نوسانگر لیزر به شمار می‌آید. در این پژوهش رفتار نمایه مدی نوسانگر لیزر Ce:Nd:YAG با دمش دیود نور‌گسیل و بستگی آن به آرایش هندسی و شدت منابع نوری مورد مطالعه تجربی و نظری قرار گرفته است. مشاهدات تجربی نشان می‌دهند که با انتخاب مناسب توزیع شدت به روش کنترل توان الکتریکی اعمال شده به دیودهای نورگسیل به‌همراه هندسه مناسب برای سامانه دمش می‌توان به گستره وسیعی از توزیع عرضی و نمایه‌های مدی اینس-گاوسی باریکه لیزر با پایداری مناسب دست یافت. بررسی‌های عددی بر پایه محاسبه نمایه عرضی توان جذب شده در واحد حجم محیط فعال و بهره به روش ردیابی تصادفی پرتوهای دمش و انتشار میدان نوری درون تشدیدگر نیز بیانگر تأثیر آرایش دمش و فاصله سطح تابنده دیودهای نورگسیل تا سطح جانبی محیط فعال بر نمایه مدی نوسانگر لیزر است.

چکیده [English]

Transverse intensity distribution or laser mode profile is one of the most important characteristics of a laser oscillator. In the present study, mode profile of a LED-pumped Ce:Nd:YAG laser oscillator and its dependency on the geometrical configuration and intensity of optical pump sources have been experimentally and theoretically investigated. Experimental observations show that with a proper pumping geometry and the control of electrical pumping power of the light-emitting diodes, a wide spectrum of stable transverse beam profiles with Ince-Gaussian mode pattern can be generated. In addition, numerical computations based on randomly ray tracing and calculation of the absorbed pump power per unit volume of the active medium, gain profile, and the propagation of optical field inside the optical resonator were confirmed the effect of the pumping configuration and distance between the emitter surface of LEDs and lateral surface of the active medium on the mode profile of the laser oscillator.
