Laser532-1HSU 532nm Raman Stable Spectrum USB-Controlled Laser

Product Introduction
The Laser532-1HSU is a 532nm semiconductor-pumped stable-spectrum laser module designed specifically for Raman spectroscopy and other optical analysis applications. Based on DPSS (Diode-Pumped Solid-State) laser technology, it provides narrow-linewidth, stable-spectrum, and stable-power laser output required by Raman spectrometers and spectral analysis instruments.
The laser module integrates a photodetector (PD) and TEC temperature-control module to improve spectral and power stability. An internal ARM-based digital MCU implements digital PID control, while optimized optical coupling and highly integrated electronics enable convenient USB software control.
The output power can be digitally adjusted from 0 to 100mW, allowing users to select an appropriate excitation power according to different samples and measurement requirements.

Working Principle
The Laser532-1HSU uses DPSS technology to generate a 532nm laser output suitable for Raman excitation. A semiconductor pump source drives the solid-state laser process to produce the required laser wavelength.
The integrated PD photodetector monitors the laser output, while the TEC cooling module controls the operating temperature of the laser system. The ARM-based MCU uses digital PID algorithms to regulate the laser parameters and maintain stable optical output.
The optimized optical coupling structure improves the efficiency and stability of the optical system. Through the USB software interface, users can digitally control the output power from 0 to 100mW. The built-in calibration program helps maintain consistency between the set power and actual laser output.
During Raman spectroscopy, the stable 532nm laser is directed onto the sample as the excitation source. The resulting Raman scattering signal can then be collected and analyzed by the corresponding spectrometer.
