High power laser diode array with an emission wavelength of 1064nm is presented. The epitaxial structure is an InGaAs/GaAsP strained-compensated single-quantum well structure. The modules CW output power can reach to 56.5W at current of 80A. Because the heat capacity of st rather shorter pulse duration and lower duty cycle
the average driving power in the laser chip is quite low
so the heating effect cemiconductor laser is very small
using pulse injection can reduce temperature rising significantly. Aould be neglected. The definite relation between lasing wavelength and chip temperature is developed. The temperature drift coefficient is 0. 45nm/K 2008 SPIE.

We report on bottom-emitting vertical-cavity surface-emitting lasers (VCSEL's) and laser arrays providing high output powers in the 980-nm wavelength regime. Single devices with active diameters of 500 m show high output powers of 1.95 W at room temperature. Its threshold current is 510 mA
and the maximum spatially averaged optical power density is 0.93 kW/cm2. A 16 elements array with 200m aperture size (250m center spacing) of individual elements shows a CW output power of 1.21 W at room temperature
resulting in a average optical power density of 1KW/cm2. The threshold current of the array is 1.32A and the lasing peak wavelength is 981.9 nm. The distinction of emission spectrums between the single device and the array is discussed.

The theory of laser cutter and the technology neck is analyzed. We can conclude that it is almost impossible to deal with the waste thick silicon wafers which are yielded in producing silicon wafers by conventional eroding or diamond cutting
when the cutting velocity equals 100mm/min
while it is also unperfected with ecumenical laser cutter without good beam quality or precise laseroptics system. It is represented that high average power and high repetition rate laser with good beam quality and precise laseroptics system are pivotal to obtain excellent cutting effect such as thick groove depth
double-layer 0.75mm thick silicon wafer can be penetrated.. The cross section is fine and the groove is narrow
rapid cutting speed
the cutting quality meets the expecting demand.
fine kerf section without considering the effect of technique. Considering laser medium thermal lens effect and thermal focal length changing with pumping power
using plano-convex high reflectivity mirror as the back cavity mirror to compensate the heat lens influence
a /4 waveplate to compensate heat -induced birefraction
utilize the Nd:YAG self- aperture effect
more than 50 W average power 1.064 um IR output is obtained with beam quality factor (M2) equals 3.19. Through the LD-Pumped Nd:YAG laser cutter we developed with short focus length negative spherical aberration focusing lens
double axis linear step motor positioning system
suitable beam expander multiplying factor
appropriate diameter of exit beam aperture
proper repetition rate
when the cutting velocity equals 400mm/min
0.75mm thick silicon wafer can be penetrated
