A Simple Model to Measure Linewidth Enhancement Factor (α) for Multi-wavelengths Semiconductor Laser
Semiconductor laser, Fabry-Pérot laser, injection-locking
2011/9/2
A novel and simple model is proposed for the measurement of the linewidth enhancement factor (LEF) α of multiwavelengths semiconductor laser. It is based on the suppression characteristics of an arbit...
A Non-linearized PLS Model Based on Multivariate Dominant Factor for Laser-induced Breakdown Spectroscopy Measurements
LIBS, partial least square, quantitative measurement laser diagnostics
2011/8/29
A multivariate dominant factor based non-linearized PLS model is proposed. The intensities of different lines were taken to construct a multivariate dominant factor model, which describes the dominant...
