[00111785]钛宝石激光放大器

一种钛宝石激光放大器,包括泵浦激光器、钛宝石晶体、多通放大器、激光种子源、同步延时器,特点是：在泵浦激光器的输出光路中加入泵浦光的半波片,在所述的钛宝石晶体的透射光路中依次加入泵浦光的四分之一波片和泵浦光反射镜。本发明不仅可以有效降低钛宝石晶体的横向增益,从而很好地抑制了钛宝石的寄生振荡,而且可以提高钛宝石晶体对泵浦光的吸收率,提高了种子光的放大效率。本发明具有调节方便、简单高效,实用性强的特点。 | The invention provides a titanium sapphire laser amplifier, which comprises a pumping laser, a titanium sapphire crystal, a multi-path amplifier, a laser seed source and a synchronous time delay. The titanium sapphire laser amplifier is characterized in that a pumping light half wave plate is added into an output light path of the pumping laser, and a pumping light quarter wave plate and a pumping light reflecting mirror are sequentially added into a transmission light path of the titanium sapphire crystal. The titanium sapphire laser amplifier has the advantages that the transverse gain of the titanium sapphire crystal can be effectively reduced, so the parasitic oscillation of the titanium sapphire is well inhibited, in addition, the absorption rate of the titanium sapphire crystal on the pumping light can be improved, and the seed light amplification efficiency is improved. The titanium sapphire laser amplifier has the characteristics that the regulation is convenient, simplicity and high efficiency are realized, and the practicability is high。
