LDX Optronics offer high power single emitter multimode laser diodes at standard wavelengths of 808, 940 and 980nm as well as “esoteric” wavelengths from 445nm to 1850nm. A wide range of open heatsink and hermetic packages are offered with options for monitor photodiode, cooling and fibre-coupling.
A new SMA-connector package offers the benefit of a removable fibre with the facility to change fibre size. Although the package can be used with any size of fibre LDX recommend that the core diameter be at least 150µm larger diameter than the stripe width of the laser diode itself in order to achieve the specified >85% coupling efficiency.
A multi-wavelength fibre-coupled module is also offered. The unit can incorporate up to 5 of LDX's 100µm emitter multimode laser diodes from 445nm to 1850nm - enabling powers from 100mW to more than 10W - depending upon the wavelengths selected. The output fibre can be 100µm, 200µm or 400µm core (0.22NA) with options such as Monitor Photodiode (MPD), PT100 thermistor and integrated thermoelectric cooler (TEC)
Laser diode bars are also offered from 660nm to 1064nm as standard with options out to 1850nm.

In many instances where LDX do not already have the wavelength required they can develop bespoke diodes to meet customers’ requirements so please contact us if you can’t find the solution for your application.
