D. High-Power and Beam-Shaped DBR Laser diodes

High-Power Package

 

Photodigm developed a special package to deal with the heat produced at high output powers, called Mercury­™ , which is a <1cm TOSA-like (Transmitter Optical Sub-Assembly) accompanied by a flex cable of 2inch (~6cm).

Available for 780, 852, 976 and 1064nm DBR Laser Diodes, for output powers up to 280mW in standard (tested up to 500mW), and for 785, 795, 830 and 895nm diodes up to 240mW.

Features:852nm_liv_on_16inch_by_21inch_foam_board-1-resized-600

  • Capacity to handle up to 1 watt of laser power
  • Built in rapid response Peltier and thermistor for closed loop feedback temperature control
  • Low thermal mass for rapid wavelength tuning
  • Small volume (<0.5 cm3 )
  • Flex cable breakout of electrical connections
  • Available test mount for laboratory use (see Photodigm model TS-1000A, shown below)
  • OEM and custom versions available
  • See Drawing here.

 

These models are particularly suitable for LIDAR applications. You may find an article about Photodigm’s collaboration with NASA in water-vapor DIAL detection here.

Beam-shaped DBR Laser diodes

 

This package can be nearly collimated thanks to a proprietary VPS microlens (Virtual Point Source) which corrects the astigmatism and reduce the divergence on the fast axis. The shaped beam is then nearly Gaussian, slightly elliptical, and can then be directly focused or collimated by a simple asphere.
