Description

Photodigms DBR Laser Diodes

The DBR Series of high-power edge-emitting Lasers are based on Photodigm's advanced singlefrequency laser technology. It provides a diffraction limited, single lateral and longitudinal mode beam. Facets are passivated for high-power reliability. Applications include spectroscopy for rubidium-based quantum encryption, chronometry, and magnetometers.

Photodigm DBR lasers - selected by engineers worldwide for the most demanding applications in spectroscopy, atom sensors, and metrology.

SPECTROSCOPY CERTIFIED

Whether you need to hit the transition lines of K, Rb, Ca, Cs, Ca+, or He* - our Photodigm Spectroscopy Certified wafelengths are guaranteed to be tunable to the relevant spectroscopic lines at a laser temperature of 25 °C ± 10 °C. Spectroscopic Certified wavelengths are unmatched precision designed specifically for atomic clocks and guaranteed to hit the specific atomic transition you need.

HIGH POWER DBR LASER DIODES

Our Photodigm High Power Laser Diodes are designed with a longer gain section and a tapered structure to deliver a high output power that ranges up to 350 mW in some wavelengths.

LOW POWER DBR LASER DIODES

Our Photodigm Low Power Laser Diodes are designed to deliver low output powers in small packages while remaining tunable.

HOTDBR LASER DIODES

Our Photodigm High Operating Temperature (HOT) DBR Laser Diodes continue to deliver optimal performance at 65 °C ± 10 °C at key Alkali-atom wavelengths for quantum sensing applications.

VIRTUAL POINT SOURCE (VSP) LENS

Photodigm's Virtual Point Source (VPS) microlens provides an integrated laser diode optics solution to decrease astigmatism and improve the circularity of the DBR laser diode's single-mode spatial output beam.

  • High efficiency in capturing the fast-axis divergence (>98%)
  • Focus the beam to near-diffraction limited performance of applications including fiber-coupling with an external single aspheric lens
  • Ideal collimation and coupling of light to external optics
  • Achive circularity of 1.0-1.2 (slow axis / fast axis diameter ratio)
