powerMir : High Power Quantum Cascade Lasers (QCL)

From your lab to series productions, we supply ITAR-free high powered QCL laser systems customized for your projects

Quantum cascade lasers (QCLs) are intersubband semiconductor lasers emitting around a center wavelength ranging from the mid-infrared.

The QCLs proposed by mirSense are high-powered diodes (typically watt-level) emitting in the main transmission bands of the atmosphere (4.0µm, 4.6µm, 4.8µm, 9.x µm). They are Fabry-Perot laser sources operating in quasi CW regime (pulsed operation down to few tens of nanoseconds and high frequency above MHz) at room temperature. The high average power and wall-plug efficiency of this product is perfectly suited for counter-measure and other defense applications.

“ The roadmap of the mirSense company is to remain the leader by reaching high powers in the wavelengths of 4µm, 4,6µm, 9µm.” says Dr. Gregory Maisons, phd, head of laser R&D at mirSense.

The QCLs from mirSense are proudly manufactured in first-class clean rooms in the heart of the French optics valley on the “Saclay Plateau” near Paris. mirSense focuses on serving industrial customers that require a high level of laser repeatability to ensure good batch-to-batch quality for series-productions. Customers will especially find with mirSense a very high beam quality.

mirSense offers a full range of ITAR-free products from chip on submount manufacturing to full turnkey systems. For OEM system integrators, mirSense manufactures a packaged diode plugged to a top-notch PCB driver that includes laser control, thermal management and security and safety. This packaged diode is the “POEM” system (POEM stands for PowerMir OEM system).

Turnkey system

 

mirSense turnkey system_LD
  • Plug-and-play system perfect to use inside a lab

  • Stand alone system including: laser head, driver, heat exchanger

  • External TTL for synchronization

  • Redlaser beam to facilitate alignment

  • User-friendly PC software allows users to:

    • Turn ON/OFF the laser

    • Easily change the operating mode (power, modulation)

For lab experiments, we offer a plug-and-play easy to use turnkey system that includes laser heads, a driver and the cooling mechanism as well as a user-friendly PC software.

In order to accompany you in your future projects, the mirSense turnkey plateform is very modular, able to control simultaneously 2 different laser heads (with different or identical wavelengths), you can have as many heads as you want a choose the two you want to operate!


POEM system (HHL packaged laser + PCB electronics)

 

mirSense POEM system
  • Compact stand-alone OEM product for system integration

  • Powerful FPGA-based architecture

  • MODBUS communication for system integration and user-friendly PC software for configuration and tests

  • External TTL for synchronization

  • Cost effective for series-productions

 

For system integration, our standard sub-system is a packaged laser supplied with its electronics driving board: the POEM system. When efficiency rhymes with simplicity, we have developed as well a top-notch PCB board to control the lasers. This board embedded unprecedent functionalities such as laser driver (Down to 20ns pulse duration and high frequency, up to 50MHz, QCW from 0 to 100% duty cycle), complex programable modulation schemes and of course full laser protection. Thanks to those extended capacities, each electronics is factory set to optimize the laser performances depending on your application needs.

The PowerMir OEM system (POEM) is meant for customers who wish to integrate a QCL high-powered source inside their system (for example a DIRCM system). Each POEM is a compact light-weight and robust system made up of a packaged QCL laser plugged to a driving electronics board. Each POEM delivers the minimum average optical power required for a set of different temperature levels of the base plate of the laser. The onboard firmware protects the laser from burning through temperature management of the TEC element. The customer can communicate with the board through MODBUS commands and a TTL trigger allows the customer to modulate each board with confidentiality.  Several POEM systems can be combined to combine and increase the total optical output power.


Packaged chips

 

mirSense HHL_LD
  • Standard high heat loads package (9-pins HHL) or custom package on request

  • Integrated Peltier TEC cooler

  • Integrated collimating lens (High beam quality, M²<1.5)

  • Possibility of chips on submount delivery

For clients who wish to purchase only the laser without the driving electronics, all of our laser wavelengths are available in a packaged version alone. Our standard offer is in a HHL package including the thermal regulation and a collimating lens. We are used to develop and supply custom packages as well.

For specific projects, mirSense can also supply QCL chips on submounts on demand.
