Plate and λ/2 plate were placed inside the Nd∶YVO4KTP green laser cavity with angle 90°between their fast axis.The composite plate composed of HWP,QWP and KTP has the function of QWP.The composite plate with Nd∶YVO4 can effectively suppress the coupling of polarized modes,and multi-longitudinal-mode lownoise green laser was obtained.Since the composite plate counteracted the phase shift induced by temperature sensitivity of quartz plate,the green laser operated with lownoise reliability in different output power and different operation temperature.The threelongitudinalmode, the noise of less than 0.5% and output power stability of less then 1% for 12 hour are obtained in the green laser.

This study on creep behavior of TiAl Polysynthetically Twinned crystals was carried out primarily to understand the effect of lamellar orientations on creep behavior in TiAl alloys with lamellar microstructure. It also provides a theory fundament for microstructure control and design for TiAl alloys.

The results show that in the case of {1 0 0}, the morphology of crystal changes from lowtemperature sheet to hightemperature tower with increasing the synthesized temperature, whereas in the case of {1 1 1} the change trend is contrary to {1 0 0}. When {1 1 1} facet or {1 1 1} was used as the growth facet, the sheetlike crystal is more difficult to incorporated for the metal inclusion regardless of synthesized temperature. With NiMnCo metal as solvent, large highquality gemgrade diamonds can also grow on {1 1 1} facet with proper temperature gradient.
