785Nm external cavity Laser Diode with volume Bragg grating used in Raman spectroscopy

A 785 nm external cavity laser diode with volume Bragg grating (VBG) used in Raman spectroscopy was presented. In order to improve the performance of Raman signal, the line-width of laser diode (LD) is narrowed by external cavity technology and VBG, and the beam is also shaped by aspheric lens and f...

Description
Summary:A 785 nm external cavity laser diode with volume Bragg grating (VBG) used in Raman spectroscopy was presented. In order to improve the performance of Raman signal, the line-width of laser diode (LD) is narrowed by external cavity technology and VBG, and the beam is also shaped by aspheric lens and fast-axis-collimator.
