摘要:
The invention relates to an optical resonator, laser apparatus and a method of generating a laser beam inside an optical resonator. The optical resonator (10) includes an optical cavity (12) and an optical element (104.1, 104.2) at either end thereof, operable to sustain a light beam (108) therein, characterised in that each optical element (104.1, 104.2) is a phase-only optical element operable to alter a mode of the beam (108) as it propagates along the length of the optical resonator (10), such that in use the beam (108) at one end of the optical resonator (10) has a Gaussian profile while the beam (108) at the other end of the optical resonator (10) has a non-Gaussian profile.
摘要(中):
本发明涉及光学谐振器,激光装置和在光学谐振器内部产生激光束的方法。 光学谐振器(10)在其任一端包括光学腔(12)和光学元件(104.1,104.2),可操作以在其中维持光束(108),其特征在于每个光学元件(104.1,104.2)是 一个仅相位光学元件,其可操作以在沿着光学谐振器(10)的长度传播时改变光束(108)的模式,使得在使用中在光学谐振器(10)的一端处的光束(108) 具有高斯分布,而在光学谐振器(10)的另一端的光束(108)具有非高斯分布。
