One of the effective method of improving diamond tool life on rulling large diffraction gratings is developing precise double-cone edged on line edge transfering tool. But traditional died weight or manual lapping technique couldn't meet the precision requirement of on line edge transfering tool. So preliminary studied rigid lapping of diamond grating ruling tool. Choosing traditional BC6063 shaping machine and made a series of alteration on it
achieved the automation of lapping process of diamond grating ruling tool. Through lapping grating ruling tool and AFM measurement find that the surface roughness of tool is 1.51nm
the radius of tool edge is 160nm
edge quality is good enough
this verified the feasibility of rigid lapping of diamond grating ruling tool and lay the foundation for developing precision lapping machine. (2011) Trans Tech Publications

As the increasing applications of the semiconductor lasers in the laser processing
the single 2-D stack optic-power density has not satisfied the actual requirements. It demands to couple several diode laser stack beams to one to improve the brightness
and it becomes the central issue to adopt the appropriate beam coupling technology which would offer high quality and high efficiency. In this paper
it mainly introduces the beam shaping and the technology of spatial coupling
polarization coupling
and wavelength coupling. The coupling key elements are presented and indicated. Finally
the development of the diode laser on beam coupling in our country fell behind through analyzing the statement of the world. Our lab is studying on polarization coupling and wavelength coupling. We gain some results by phase
which the polarization coupling efficiency can achieve 90% for two LD stacks with seven bars whose luminous wavelength is 975nm and980nm.By two 808nm diode laser coupling
the efficiency of 60% can be achieved after focusing to the beam size of 22mm2. 2008 SPIE.
