TO Package
TO5.6mm / TO9.0mm
The standard package for semiconductor lasers. Laser light is emitted vertically through the aperture on the top surface at a beam angle specified for each model. Depending on the product, a photodiode and/or a Zener diode may be included.

TO Package with Lens
TO with a Collimation Lens / TO with a Fiber Receptacle
Optics are integrated with the TO package. Either by incorporating a collimation lens to ensure that the emitted laser light is collimated, or with a receptacle mechanism designed to facilitate the coupling of optical fibers.
Line up
Side Lead Package
The lead pins are mounted on the side of the package, and the laser beam is emitted horizontally from the side of the package. Its design enables the integration of high-power LD chips with long cavity lengths.
Line up
Multi-chip Package
OctoLas™ / QuaLas™
Multiple LD chips are integrated into a single package. The laser light is emitted in a vertical array. This enables more sophisticated integration within a smaller footprint compared to using individual packages.

Featured Technologies
DFB (Distributed Feedback) LD
Transverse single-mode semiconductor laser in which a grating pattern is built near the active layer inside the laser chip along the waveguide direction. It enables single-frequency laser oscillation. It is useful for applications requiring narrow spectral linewidths, such as interferometric metrology and Raman spectroscopy.
DBR (Distributed Bragg Reflection) Multi-Mode LD
A grating pattern is built into the front section of a high-power transverse multi-mode LD. It provides a narrower spectral linewidth than conventional Fabry-Pérot-type LDs, making it suitable for applications such as interferometric metrology and Raman spectroscopy. It is also well suited for wavelength beam combining techniques to achieve higher output power.
Fiber-Coupled Multi-Color Laser Unit (Featuring QuaLas™)
Laser beams from multiple QuaLas™ modules are coupled into a single optical fiber. Multiple wavelengths and output power levels are available by customizing the number of LD chips and their wavelengths in the QuaLas™ modules. Utilizing DBR-LDs enables highly precise spectral control. It is useful for applications requiring multiple wavelengths, such as wafer inspection, fluorescence, and other industrial lighting applications.
