The TCMarshall and others a strong pump field 1 ~ 3mm band free-electron laser amplifier experiment, to successfully generate several megawatts of power of the laser [3]. Despite the power and

efficiency of these earlier principle experiments are very low, but the potential characteristics and advantages of the free-electron laser, was soon subject to the attention of scientists to

promote the free-electron laser in the world within the experimental work carried out . With the early experimental work carried out at the same time, a variety of theoretical studies have been

published. In March 1983, U.S. President Ronald Reagan proposed the Strategic Defense Initiative "(Strategic Defence Initiative, referred to as SDI plan). The high power green laser pointer will be

manufactured in the torch shape.
Due to a series of advantages of the free-electron laser as part of the main candidates for which ground-based laser weapon. Thus from 1985 onwards, the development of free-electron laser has

obviously been "SDI" plan and promote the world free-electron laser research boom. France, Russia, Britain, Germany, China, Japan, the Netherlands and other countries have carried out work in this

area [10]. The free-electron laser as a family member of the laser, from the advent of the beginning of its unique features attracted the attention of the people. In the field of civil and military

applications of communications, radar, plasma heating, laser spectroscopy has an attractive prospect. Characteristics of the free-electron laser. So many choices of green laser pointer can be

provided for customer.
The free-electron laser is the birth of the last century since the 1970s a new type of laser device is the forefront of one of the world's high-tech science and technology in the laser arena, the

free-electron laser with ordinary laser monochrome and directional coherence The high brightness compared to the outside, but also has the following features: adjustable frequency, wide tuning

range. The free-electron laser is a monochromatic coherent light, the wavelength varies with the electron beam energy, the electron beam energy of the electron accelerator output can easily be

adjusted considerably within the spectrum of the free-electron laser to far-infrared across to the hard X-rays, while the vast majority of the laser can only be fixed to the wavelength.
