878.6nm (VBG) Fiber Coupled Diode Laser

1. Primary Pumping Applications (for Yb³⁺ doped gain media):

High-Power Yb-doped Fiber Lasers: Main pump source for industrial kW-class lasers used in metal cutting, welding, and additive manufacturing.
Yb-doped Solid-State/Crystal Lasers: Pump source for high-energy/ultrafast (femtosecond) laser amplifiers used in precision micromachining and scientific research.
Ti:Sapphire Laser Pumping: An efficient pump source for ultrafast and broadly tunable lasers (an alternative to 532nm pumps).

2. Scientific & Precision Applications:

Frequency Conversion Pumping: Used to generate visible (green/yellow) and UV light via nonlinear processes (SHG, SFG).
Quantum Optics & Cold Atoms: Acts as a repump or pump laser in experiments with ytterbium atoms for optical clocks and quantum simulation.

3. Direct Use Applications:

Biomedical Imaging: Potential light source for Optical Coherence Tomography (OCT) and fluorescence excitation within the biological tissue window.
Core Advantage: The VBG provides precise wavelength locking at the strong Yb³⁺ absorption peak (878.6nm), enabling highly efficient and stable pumping.
