Method for improving performance of wavelength beam combining diode laser systems

A process monitoring system determines a spectral response of a process material. This system has a tunable laser for generating an optical signal that is wavelength tuned over a scan band and an optical probe for conveying the optical signal to the process material and detecting the spectral response of the process material. The optical probe expands a beam of the optical signal to a diameter of greater than 10 millimeters. This avoids one of the difficulties with monitoring these process applications by ensuring that the spectroscopy measurements are accurate and repeatable. It is desirable to sample a relatively large area of the processed material since it can be heterogeneous. Additionally the large area mitigates spectral noise such as from speckle.

Spectroscopy probe and material processing system

A probe of a Raman spectroscopy system has a wavelength and/or amplitude referencing system for determining a wavelength of the excitation signal. Preferably, this referencing system is near an output aperture, through which the excitation signal is transmitted to the sample. In this way, any birefringence or polarization dependent loss (PDL) that may be introduced by optical elements in the system can be compensated for since the wavelength reference system will detect the effect or impact of these elements.
