Efficient improvement of laser beam quality by coherent combining in an improved Michelson cavity
by Qinjun Peng, Zhipei Sun, Yahui Chen, Lin Guo, Yong Bo, Xiaodong Yang, Zuyan Xu
The efficient improvement of laser beam quality is demonstrated by coherent combining of two $Nd : Y V O_{4}$ lasers in an improved Michelson cavity. When the two lasers are separately operated with beam qualities of $M_{x}^{2} = 1.74$ and $M_{y}^{2} = 1.34$ for laser 1 and $M_{x}^{2} = 1.53$ and $M_{y}^{2} = 1.39$ for laser 2, by coherent combining of the two lasers, a single beam output exceeding $2 W$ with a nearly perfect ${TEM}_{00}$ mode $(M_{x}^{2} = 1.08, M_{y}^{2} = 1.04)$ is obtained. Moreover, it can withstand environmental perturbations with no change in beam quality or output power and has the potential for scaling to much higher output power with high beam quality by coherent addition of multiple lasers in this configuration.

A microcylindrical lens array made of silver-halide-sensitized gelatin etched by an enzyme with a real-time mask
by Qinjun Peng, Yongkang Guo, Jianhua Zhu, Yangsu Zeng, Shijie Liu
A novel method has been developed to fabricate microcylindrical lenses by etching silver-halide-sensitized gelatin (SHSG) with an enzyme solution, and the exposure pattern is produced on SHSG through a real-time mask technique. In this paper the principle of etching SHSG with an enzyme solution is given in detail and the optimum technique parameters of this process are presented; furthermore the theoretical analysis and solving scheme for the nonlinearities which arise from the absorption of light energy by film are given. A good linear relationship is experimentally obtained between the etching depth and time in depth a range up to 4 μm. Finally, the microcylindrical lens is achieved by experiment. The results are evaluated for experiments with a stylus profiling instrument and scanning electron microscope. This method does not require the use of expensive equipment, and it is not sophisticated and time consuming. So it is a practical method to fabricate excellent micro-optical elements.

Multiple fractional Fourier transform hologram by use of holographic lens
by Yangsu Zeng, Yongkang Guo, Yixiao Zhang, Fuhua Gao, Qinjun Peng
A new method is presented to record multiple fractional Fourier transform holograms by use of a holographic lens. With holographic lenses, several fractional Fourier transform holograms of different objects can be recorded in a simple way, and images of these recorded objects can be reconstructed in different positions and directions in three-dimensional space. In this paper, the theory and characteristics of the hologram recorded using the holographic lens are analysed. Using this method, a multiple fractional Fourier transform hologram was fabricated, with satisfactory results.

Real-time gray-scale photolithography for fabrication of continuous microstructure
by Qinjun Peng, Yongkang Guo, Shijie Liu, Zheng Cui
A novel real-time gray-scale photolithography technique for the fabrication of continuous microstructures that uses a LCD panel as a real-time gray-scale mask is presented. The principle of design of the technique is explained, and computer simulation results based on partially coherent imaging theory are given for the patterning of a microlens array and a zigzag grating. An experiment is set up, and a microlens array and a zigzag grating on panchromatic silver halide sensitized gelatin with trypsinase etching are obtained.

Implementation of image encoding and decoding with computer-generated hologram of fractional Fourier transform
by Yongkang Guo, Yangsu Zeng, Shiwei Xie, Fuhua Gao, Jianhua Zhu, Yixiao Zhang, Qinjun Peng, Jinglei Du, Jin Zhang
A new method is presented to encode and decode images with computer-generated hologram of fractional Fourier transform. The fractional Fourier transform computer-generated holograms (FRT-CGH) of several objects with different orders are respectively recorded on one holographic plate. In order to reconstruct images of the objects, several fractional Fourier transform systems of certain orders are needed. This method is agile and convenient on design and fabrication. It can be encoded and decoded either by numerical method or by optical method. Because of its particularity of image reconstruction, FRT-CGH is regarded as a new optical security system and may be widely used in the future.
