Review of laser-diode pumped Ti:sapphire laser

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 blue-green 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.

Automated summary

With the development of high-power blue-green laser diodes, low-cost LD directly pumped Ti:sapphire lasers have been further promoted and achieved significant results in the fields of optical frequency combs, multiphoton microscopy imaging, and so on.
