Broadband near‐infrared (NIR) phosphor‐converted light‐emitting diodes are next‐
generation smart NIR light sources. However, the NIR phosphor suffers from serious thermal …

We report detailed experimental data aiming for rigorous investigation of Tm: YLF laser
performance, especially with a focus on tuning behavior. Continuous-wave (cw) lasing …

The chromium ion is among the most widely explored and used laser-active ions.
Depending on the charge state of the laser-active chromium ion in the host, tunable …

All-solid-state tunable lasers have been widely used in many fields including multi-photon
microscopy, time-resolved photoluminescence, atomic physics, and so on owing to their …

We present spectroscopic measurements focusing on a detailed investigation of
temperature dependence of absorption, emission and gain in the uniaxial Yb: YLF laser gain …

A new near-infrared tunable laser crystal, Cr 3+ doped Ca 3 (VO 4) 2 crystal (Cr: CVO) is
grown by the Czochralski method for the first time. The crystal structure and thermal …

Cr: Colquiriites (Cr: LiCAF, Cr: LiSAF, and Cr: LiSGaF) are well-known for their broad
emission bands in the near-infrared region. Unfortunately, due to their relatively weak …

We have investigated the cryogenic performance of Yb: YAG and Yb: YLF crystals in rod-
geometry to understand the pros and cons of each material for the development of ultrafast …

We have demonstrated widely tunable Yb: fiber-based laser sources, aiming to replace Ti:
sapphire lasers for the nJ-level ultrafast applications, especially for the uses of nonlinear …

We have achieved stable passively Q-switched mode-locked (QML) operation in a Cr: LiSAF
laser. In the experiments, a 10 mm long,% 1.5 Cr-doped LiSAF crystal was pumped by two …
