Ti:sapphire laser has an important position in ultrashort pulse generation and wavelength tuning. The use of expensive frequency-doubled diode-pumped solid-state laser as the pump source limits the promotion of its application to a certain extent. With the maturity of high-power bluegreen laser diodes (LDs), low-cost LD directly pumped Ti: sapphire laser becomes possible. After more than 10 years of development, the output parameters of LD pumped Ti: sapphire lasers have been greatly improved. Moreover, the lasers have been applied to optical frequency combs, multiphoton microscopy imaging, and so forth, both of which have achieved impressive results.

“…It was crucial for crystal growth to control the distribution of temperature and atmosphere in the growth chamber, especially near the crystal molten cap [5][6][7][8][9][10] . In the process of crystal growth, the too large radial temperature gradient of the growth chamber, especially near the crystal molten cap, is easy to cause the too low edge temperature of the flat molten cap, as shown in figure 1a, which makes the crystal size less likely to grow, or even shrink.…”

Combustion characteristics of three-tube burner in growth chamber for preparation of single crystal by the Verneuil method were investigated, and the effects of nozzle structure and flow rate on the surface temperature of molten cap were analyzed. The results showed that hydrogen flowed out from the nozzle diffused with inner and outer oxygen, and two flame produced in the center and near the wall of growth chamber. The surface temperature of molten cap were gradually reduced from the center outward. The temperature of molten cap decreased gradually with increasing the nozzle aperture of inner oxygen, and varied slightly with the diameter of hydrogen and outer oxygen nozzle. The temperature of molten cap decreased gradually with increasing the flow rate of inner and outer oxygen, while increased with the flow rate of hydrogen.
