True Gaussian

True Gaussian Performance

Osela’s True Gaussian Laser (TGL) uses unique optical technology to produce a fiber-like diffraction limited beam in a compact standalone free space module.

The technology allows for maintaining of a high Gaussian fit (> 95% ) over a long working range with no secondary lobes that are typically found with direct diode lasers. An example can be seen below of the TGL solution vs a standard diode laser.

True Gaussian Laser

Another advantage of the TGL is its ability to project circularized laser beams from direct laser diodes while maintaining its true Gaussian performance. While many other current market solutions offer circularization, it does so at the expense of beam quality. A typical TGL beam aspect ratio vs working range can be seen in the graph below.

Modulation

The Compact laser can be modulated by an external 0 to 5V TTL signal via the white wire. The “T” type modulation is the default input for the Compact laser module.
