Laser bars

Laser bars are arrays of single laser emitters, which can be mounted and used as such, often with collimating optics in order to make the laser beam rectangular. Bars can be used in free-space applications, such as illumination and pumping, or the laser light can be coupled into multi-mode fiber, allowing many more uses. When even more power is needed, bars can be stacked to form a two-dimensional, even brighter laser array.

In the below table, there are some examples of our products. If you can’t see what you are looking for, just let our sales team know what you wish to have.

Optical Output Power *) 4 W 4 W 10 W 10 W 40 W 60 W 40 W 60 W 100 W 20 W 20 W


Laser bars can also be processed so that each emitter can be controlled individually, i.e. individually accessible bar, IAB. These types of lasers can be used in printing, for example. As an original semiconductor laser manufacturer, Modulight is able to do customized semiconductor diode solutions. When you need a custom laser product, please let us help you.
