With the advantages of small volume light weight high efficiency and long lifespan diode laser has been widely applied to industrial processing. Presently for laser used as processing light source needs to amount to dozens of KW per cm2 of power density how to increase power output and get smaller light spot for diode laser becomes a key problem. It is introduced that by designing beam shaping by ourselves and making use of optical system for beam blooming and focusing 808nm laser array composed of 20 bars eventually achieves the 1001.5w power output coupling efficiency at 90% 11mm2 of light spot through experiments which enables diode laser to be directly applied to cladding welding and so on. 2012 IEEE.

In high power TEA CO2 laser system liquid crystal display (LCD) module is a key device for display and control functions. Because of laser's harsh electromagnetic environment LCD module coupled to the electromagnetic interference easily leading to not work normally. This paper analyzed the interference coupling mechanism. On the basis of the analysis results LCD module's field-line coupling is calculated by Taylor form's BLT equation. The calculation result is verified by experiment. The results show that due to the field-line coupling the data line of LCD module existed interference voltage interference voltage value is 1V. The interference voltage is larger than the LCD module's noise margin. LCD module must shield the interference. 2012 IEEE.

In the paper real-time control and calibration on laser energy simulator is studied which is based on Optoelectronic confrontation hardware-in-loop (HWIL) simulation test system. The control of the laser energy is necessary in simulation system and it is vital to make the test successfully. The laser energy simulator simulates the attenuation process and the changing of laser energy by the continuous rotation of Glan prism. To get high accuracy of laser power outdoor the accurate calibration of the rotation position and the attenuation process in energy simulator is necessary. We apply dual calibration on the laser energy simulator and the feasibility was proved by the calibration data. 2011 IEEE.

The strong electromagnetic interference (EMI) generated in high-power TEA C02 laser system mainly comes from main discharge circuit pulse spark switch and power supply. Such strong EMI causes great damage and interference to the control system based on DSP. In this paper we present the interference sources and their distribution and propose the methods of anti-interference. Measures for hardware design include weakening transient ground potential difference by using equipotential lines between devices using signal isolation interface to inhibit the transient ground potential interference and rational layout shielding and filtering to the control system. And methods for software design include range-limited filter self-diagnosis and self-repair for the critical data and anti-interference during abnormal reset. The EMI has been inhibited effectively by the anti-interference method proposed above. The result shows that: the software anti-interference method is as important as the hardware anti-interference method for the control system in a complex environment of strong EMI. 2010 IEEE.

808nm high power diode lasers which is rapidly maturing technology technically and commercially since the introduction in 1999 of complete kilowatt-scale diode laser systems have important applications in the fields of industry and pumping solid-state lasers (DPSSL). High power and high power conversion efficiency are extremely important in diode lasers and they could lead to new applications where space weight and electrical power are critical. High efficiency devices generate less waste heat which means less strain on the cooling system and more tolerance to thermal conductivity variation a lower junction temperature and longer lifetimes. Diode lasers with Al-free materials have superior power conversion efficiency compared with conventional AlGaAs/GaAs devices because of their lower differential series resistance and higher thermal conductivity. 808nm GaAsP/GalnP broad-waveguide emitting diode laser bars with 1mm cavity length have been fabricated. The peak power can reach to 100.9W at 106.5A at quasicontinuous wave operation (200s 1000Hz). The maximum power conversion efficiency is 57.38%. Based on these high power laser bars we fabricate a 1 3 arrays the maximum power is 64.3 W in continuous wave mode when the current is 25.0A. And the threshold current is 5.9A the slope efficiency is 3.37 W/A. 2008 SPIE.
