Review of laser‐diode pumped Ti:sapphire laser
Microwave and optical technology letters (Print), 2021 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.

Alexandrite lasers with blue-diode-pumping
Optics Express, 2023 The availability of high-power and high-brightness blue diode lasers makes them attractive as low-cost pump sources for broadly tunable Alexandrite lasers. In this paper we investigate the performance of an Alexandrite laser pumped by a high-power fiber-delivered blue diode module.
