Compact fulltime low noise laser diode modules for next generation bio-medical photonics devices

Abstract:

   Laser diode modules offer many physical and electronic advantages over diode-pumped solid state (DPSS) lasers when incorporated into biomedical photonics devices. Laser diode modules are smaller, more efficient, longer  lasting, and more versatile than DPSS lasers.  In addition, laser diodes  provide an abundance of available wavelengths in the ultraviolet, visible,  and infrared, including the colors commonly used in biomedical  instrumentation.
  The compact and economical nature of diode laser sources  are allowing the development of urgently needed low-cost, point-of-care (POC) biophotonic tools, moving critical testing from centralized  laboratories to clinics, bedsides, or even the home. Historically diode  laser limitations have included wavelength (spectral) instability, unstable  longitudinal mode structure, high periodic noise spikes, and generally poor  spatial mode structure. By combining laser diodes with Pavilion  Integration's proprietary electronic stabilization technology we demonstrate that many of the limitations are eliminated, and a high-quality optical beam with ultra-low intensity noise, low speckle and superior wavelength stability is produced.
