very stability
3.After an additivecoloration for the crystal,we demonstrated the following continuously tunable color centerlaser operation:a peak power output of 22mW at the wavelength of 2.65μm with the tuningrange of about 0.4μm was obtained by using the Ar~+ pump laser of 2.5W power at0.514μm. Output power keeps a very high stability and crystal homogeniety is verygood.
