Mid-IR DFB Interband Cascade Laser 2900 – 4000nm

We divide our lasers into wavelength regions.

So when we say range 2900nm to 4000nm that is a region to classify our lasers. But then the individual laser will be centered at an specific wavelength. Usually our lasers tune a few nm, the higher the wl the more nm that the laser can be tuned, but is always below 5nm if tuned only with current, even less (depending on the wl).

“so your stating that this laser will emit at 2800 with the same performance.”->no we did not stated that.

What is the method to shift the wavelength? ->usually by current, and it can be done with temperature as well.

in our implementation will will want to fix this emission.-> if they want a fixed wl, then they need that temperature and current of the laser stay stable.

can this be done by your company in the event that we implement this into our systems?-> that has to be controlled by the laser driver, we do not manufacture laser drivers,

and is there OEM pricing available? -> which exact wavelength?, how many units?, is TO66 mounting ok for them?

Can I also get pricing information as well as what systems need to be installed to support this,

ie heat sinK? -> all our lasers are provided with an internal TEC, which controls the temperature.

In labs and universities we sometimes deliver an external heatsink (see attached “cube.pdf” file) which helps in the setup and fine control of temperature. Would that be useful for your customer?

controlled temperature? what is the electrical diagram look like to implement this type of emitter,-> see attached electric circuits.

what is the emission FOV?-> The expected degrees of the emitted beam are the below ones, please note that this can change with the individual laser, but is a good approximation.

As well we can offer collimated beam mounted in the heatsink if needed (usually requested by University students)
