RTI Semiconductor Laser (RSL) - comparison to regular diode modules

RTI Semiconductor Laser - new semiconductor module technology

The new laser module technology of Ray Technologies changes the way professional laser systems are built. The compact form factor and the great visibility combined with the quality of the beam profile enable higher laser power in a smaller housing compared to previous show laser systems. The beam quality has also been improved greatly, as can be seen in the picture below.

Competing products use the currently common module setup that results in rectangular or ellipsoidal shaped beam spots with different divergence values for x- and y-axis. This leads to significant color shades the longer the projection distance is, which negatively influences on the quality of the projection. The new RTI modules are designed in a way to keep spot size as well as divergence equal on both x- and y-axis. This is significantly advantageous over solutions used by competitors.

The modules are built in a way that there is no need for realignment anymore. Each module is built encapsulated and sealed, so the modules are completely maintenance free. The form factor of the new modules is standardized, like with the well-known Coherent OPSL heads, and thus can easily be combined and fit into slot-type housings. They fit into OPSL head sized slots.

In general the new modules add a lot of additional performance to the new generation of RTI & tarm laser systems but prices stay the same.

Example: RTI PIKO RGB 28

The beam specifications of the new RTI PIKO RGB 28 are given with only 4.5 mm diameter and less than 0.9 mrad divergence - which applies to both axis, so it’s an actual value and provides higher quality results than specifications with mixed calculations. The extremely small beam diameter allows for the use of very small 4 mm mirrors, which results in reduced inertia and thus very good scanning performance.
