What is a Laser Diode?

A Laser Diode or semiconductor laser is the simplest form of Solid-State Laser.  Laser diodes are commonly referred to as edge emitting laser diodes because the laser light is emitted from the edge of the substrate or chip. The light emitting region of the chip is commonly called the emitter.  The emitter size and the number of emitters determine output power and beam quality.

Electrically speaking, a laser diode is a PIN diode. The intrinsic (I) region is the active region. The N and P regions provide the active region with the carriers (electrons and holes). Initially, research was carried out using P-N diodes. However, all modern devices utilize the double-hetero-structure implementation. This design confines the carriers and photons, allowing a maximization of recombination and light generation.

Laser Diode Epitaxy: the epitaxial structure of a diode laser is typically grown utilizing one of the crystal growth techniques, starting with an N-doped substrate, then growing the I-doped layer (active region), proceeded by the P-doped layer, and finally, a contact layer. The active region of the chip typically consists of quantum wells. These wells allow for a lower threshold current and a higher operating efficiency.

Laser Diode Products

Laser Diodes

Laser Diodes are available with wavelengths in the UV, violet, blue, green, red, NIR, SWIR, MWIR, and LWIR spectral regions, in a large range of output powers.

Our single-mode products provide output powers in the mW range. Next, our multimode emitters and VCSELs produce powers in the Watts range. Finally, our diode bars, stacks and multi-emitter, fiber-coupled modules and systems provide powers in the multi KW range.

Our narrow linewidth options utilize DFB (distributed feedback) and VBG (volume Bragg grating) technology.  Furthermore, we offer fiber-coupled options on most devices and complete turn-key systems if preferred.

There are many different packages to choose from. For example, we offer chip on submount, B-mounts, C-mounts, Q-mounts, and various TO-Can and HHL packages, amongst others. Furthermore, if you do not see the package type needed, we offer many custom packages.
