    • A method of fabricating micro crystal fiber lasers and frequency-doubling crystal fibers is disclosed. The micro crystal fiber laser contains gain crystal fibers, frequency-doubling crystal fibers, and a semiconductor laser. The semiconductor laser provides a laser beam. The gain crystal fibers receive the laser beam and generate a base-frequency beam. The frequency-doubling crystal fibers have a polarization alternating period. The frequency-doubling crystal fibers are coupled to the gain crystal fibers to double the frequency of the base-frequency beam and provide a double-frequency beam with the required wavelength. In addition to providing a monochromic crystal fiber laser, the crystal fiber lasers in red, green, and blue light may be combined into an array, providing a color laser. The frequency-doubling crystal fiber can be formed using the LHPG method. During the production process, a polarization alternating external field is continuously imposed on the frequency-doubling crystal fiber, resulting in a polarization alternating period.
    • 公开了一种制造微晶纤维激光器和倍频晶体光纤的方法。 微晶光纤激光器包含增益晶体光纤,倍频晶体光纤和半导体激光器。 半导体激光器提供激光束。 增益晶体光纤接收激光束并产生基频光束。 倍频晶体光纤具有极化交替周期。 倍频晶体光纤耦合到增益晶体光纤,使基频光束的频率加倍,并提供具有所需波长的双频光束。 除了提供单色晶体光纤激光器之外,红色,绿色和蓝色光的晶体光纤激光器可以组合成阵列,提供彩色激光。 可以使用LHPG法形成倍频晶体光纤。 在制造过程中,极化交变的外部场被连续施加在倍频晶体光纤上,导致极化交替周期。
