ABSTRACT We demonstrate operation of a simple and reliable water-cooled femtosecond laser running at 10 kHz suitable for industrial micromachining applications. A laser geometry involving only a regenerative amplifier and delivering 3.5 W average power 60-fs pulses is compared to a more conventional architecture using an additional multi-pass amplifier. Both laser systems require a moderate pumping laser of similar to 30 W average power and deliver high-quality beams (M-2<1.2). (c) 2007 Optical Society of America.

    ABSTRACT: The first experimental results on a fiber laser system that generates femtosecond pulses with an energy of 1 μJ at a wavelength of 1086 and an energy of 300 nJ at a wavelength of 543 nm are presented. The pulse parameters at a wavelength of 1086 nm are optimized with respect to the effective frequency doubling. The high-energy fiber system makes it possible to solve several problems in the femtosecond material processing.

    ABSTRACT: This study presents an alternative method for micron-resolution patterning of a sapphire surface utilizing the characteristic of an ultra-short pulse (10−15 s) from ytterbium (Yb) femtosecond laser (FS-laser) irradiation. Conventional processes often involve several steps, such as wet chemical or dry etching, for surface structuring of sapphire. In this study, two-dimensional array patterns on the sapphire surface with an area of 5×5 mm2 and a depth of 1.2±0.1 μm can be directly and easily fabricated by a single step of the FS-laser process, which involves 350-fs laser pulses with a wavelength of 517 nm at a repetition rate of 100 kHz. The measured ablation depths on the sapphire surface display that the proposed process can be under well-controlled conditions. Based on the design changes for being quickly implemented in the micromachining process, a FS laser can be a promising and competitive tool for patterning sapphire with an acceptable quality for industrial usage.

    ABSTRACT: This study presents the micromachining of CuIn"xGa"("1"-"x")Se"2-based (CIGS) solar photovoltaic (PV) modules using an infrared (IR) ultrafast laser ablation setup, which is composed of a femtosecond laser source, galvano-mirror scanner and high-precision motor driven stages. Herein the three thin films (including back contact, absorber and front contact layers) of CIGS PV modules are used a one-time scribing technique. In this work, we propose to use the integrated laser system with a high repetition rate (100kHz) and an optimized energy density (fluence) threshold to achieve precise machining quality and acceptable throughput for the process of CIGS PV modules.
