【摘要】 激光一经问世,便在许多领域中得到了大规模的应用。由于大功率激光器具有较高的输出功率,在许多方面都有着重要应用,光通信领域中的光源就是激光。可以说,如果没有激光,就不可能有现代光通信技术。对于大功率的激光器来说,一般增加泵浦的能量能提高功率。过去,对于激光器的泵浦方法,采用直接单向泵浦法使激光增益介质从一个泵浦源中获得能量,从而形成粒子数反转,最后形成激光输出。但是,单一泵浦源对于激光增益介质提供的能量是有限的,不能满足大功率激光器的需求。为此,对泵浦的方式进行了改进,即采用双向泵浦的方式,对激光器的结构进行设计,为激光器提供更大的能量,由此可以得到大功率的激光输出。更多还原

【Abstract】 As soon as laser was invented,it was widely used in many fields.High power laser has many im portant applications because of its high output power.In the field of optical communication,the light source is laser.It can be said that without the laser,there would be no modern optical communication technology.For high power laser,the general way to increase its power is to increase the pump energy.In the past,the direct and one-way pumping method was used to pump the laser gain medium from a pump source,resulting in particle number inversion and finally laser output.However?the energy provided by a single pump source for the laser gain medium is limited and cannot meet the needs of high-power lasers.To this end,the way of pumping is improved,the way of bidirectional pumping is adopted,and the structure of the laser is designed to provide more energy for the laser,so that the high power laser output can be obtained.更多还原
