Fiber Laser Pump Diodes: How to Choose Wavelength, Architecture, and Package
How to specify fiber laser pump diodes: 915 vs 976 nm, single emitter to bar stacks, brightness and NA, FBG stabilization, combiners, and packaging.
Pump Diode Wavelength Drift and TEC-Less Design
The thermoelectric cooler is the part of a pump module nobody wants and most designs end up carrying. It draws power you do not have on a UAV, occupies volume you do not have in a handheld unit, adds a control loop that can fail, and introduces solder joints that fatigue under thermal cycling on […]
What Is Laser Pumping? How Pump Sources Determine Laser Performance
Laser pumping explained: population inversion, optical vs electrical pumping, end vs side pumping, quantum defect, and how to choose a pump diode that holds spec.
Pump Wavelength Selection: What Quantum Defect and Fluorescence Lifetime Actually Tell You
Quantum defect and fluorescence lifetime decide your pump wavelength. A worked comparison of 808, 878.6, 885, 888, 915, 976 and 793 nm for laser designers.
Single Mode vs Multimode Fiber Coupled Laser Diodes: How to Choose
Single mode vs multimode laser diodes: beam quality against power, the transverse/longitudinal ambiguity, fiber core and NA, and how to pick the right one.
