Thermal and population lensing of Yb:YLF at cryogenic temperature
(2023)
We present what is, to our knowledge, the first detailed study of thermal and population lensing in cryogenically cooled Yb:YLF. Using a rod-shaped a-cut Yb:YLF crystal, the thermal lens strength is measured as a function ...
Cr: Colquiriite Lasers: Current Status and Challenges for Further Progress
(Progress in Quantum Electronics, 2019)
Cr: Colquiriite laser materials (Cr:LiCAF, Cr:LiSAF, Cr:LiSGaF) own broad absorption bands in the visible region that allow direct-diode pumping by well-developed low-cost red diodes. Moreover, they possess broad emission ...
Broadly tunable two-color lasing of Cr:LiCAF with on-surface and off-surface optical axis birefringent filters: performance comparison
(Applied Optics, 2022)
We studied the two-color lasing performance of a Cr:LiCAF laser using crystal quartz on-surface and off-surface optical axis birefringent filters (BRFs). Four different on-surface optical axis BRFs with thicknesses of 2 ...
Temperature dependence of the emission cross-section and fluorescence lifetime in Cr:LiCAF, Cr:LiSAF, and Cr:LiSGaF between 78 K and 618 K
(2023)
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 thermomechanical strength, average powers from ...
Temperature Dependence of Emission Cross Section and Fluorescence Lifetime of Cr:Colquiriites in 78-618 K Range
(Optica Advanced Photonics Congress 2022, 2022)
We have measured the temperature dependence of fluorescence lifetime and emission cross section in Cr:LiCAF, Cr:LiSGaF and Cr:LiSAF in the 78-618 K range. Our results confirm their potential as high-power ultrafast sources ...
Passively Q-switched Cr:LiCAF laser with a saturable Bragg reflector
(Applied Physics B: Lasers and Optics, 2021)
We present a low-cost multimode diode pumped passively Q-switched Cr:LiCAF laser operating near 800 nm. AlGaAs-based saturable Bragg reflectors (SBRs) were used for passive Q-switching. The system is experimentally ...
