MT Transverse magnification All of the usual paraxial quantities may be calculated with the help of the ray-trace matrices given at the end of this product guide. Typically, the laser diode is collimated with one lens and a second lens is used to focus the beam. Laser diode collimators are used to collimate the highly divergent beam that is emitted by a laser diode. On the other hand, the emission bandwidth is usually quite small, so that achromatic optics are not required in most cases. EFL Effective focal length (from rear primary plane to rear focal plane) These cookies do not store any personal information. Collimators for Broad-area Emitters, Diode Bars and Diode Stacks: the emitting region of a broad-area laser diode is much larger in the direction along the wafer surface (often called the horizontal direction) than in the other one; this kind of laser design is chosen to obtain substantially higher output powers.

Singlet Construction Figure 1: Simple laser diode collimator. A long focal length lens is used to compensate for the astigmatism and then the collimating lens can provide a beam that has little divergence in both axes. Therefore, the beam quality in that direction is far worse. Storage The dependence of √A and N0, on wavelength is described by the dispersion equations listed at the end of this product guide.

A consequence of that is that while the beam diameter after a simple collimation lens is significantly smaller in the “slow” direction, the residual beam divergence in that direction is much larger. Viewed in this way, the pitch is the spatial frequency of the ray trajectory. The present invention related to optical collimating systems and has particular reference to beam compression of laser diode emission. Cylinder and rod lenses are available for beam sharpening, astigmatism correction, and line generation with diode lasers. Cavities of single-mode laser diodes are in the range of hundreds of microns.
