Recent progress in yellow laser: Principles, status and perspectives

Dy3+ and Tb3+ codoped mixed garnet crystals with a high-disorder structure for promising efficient InGaN laser-diode pumped yellow lasers

“…Currently, there are two main approaches used to develop yellow lasers: dye lasers and nonlinear frequency conversion methods. Nonlinear frequency conversion methods encompass various techniques such as dual-wavelength sum frequency, 2 optical parametric oscillators (OPOs), 10 fiber or solid-state Raman lasers, 2 etc. However, both dye lasers and nonlinear frequency conversion methods have their limitations.…”

“…Consequently, yellow laserbased light therapies have gained widespread usage in treating corneas, aortic aneurysms, and skin diseases. [2][3][4] Within the industrial sector, yellow light exhibits exceptional performance in penetrating fog, making it extensively employed for warning lighting, landscape illumination, and stage displays. 5 In scientific applications, the 589 nm yellow laser finds utility in exciting the D-line and resonantly exciting the sodium atom layer at altitudes of 80-100 km, leading to the generation of high-brightness fluorescence radiation in the dorsal direction.…”

High stability and low noise laser-diode end-pumped Nd: YAG ceramic passively Q-switched laser at 1123 nm based on a Ti3C2T x -PVA saturable absorber

“…[4][5][6] Additionally, the 561 nm yellow-green laser generated by the frequency doubling 1123 nm is an ideal laser source for dermatology, bioluminescence detection, and holographic storage. [7][8][9] However, the absence of active frequency selection and filtering results in significant output noise in the 1123 nm pulsed laser. This is due to the fact that the Nd: YAG crystal or Nd: YAG ceramic generates three spectral lights at 1112 nm, 1116 nm and 1123 nm through stimulated emission.…”
