The C-LAS laser is classified in the laser class IV. This means that the radi - ation can cause damage when it is directly applied to any tissue and also if the radiation is scattered or reflected.
To avoid any injuries it is important to follow the laser safety instructions: 1. Any user of the C-LAS laser system has to be trained by A.R.C. Laser au- thorized personal or by someone trained by A.R.C. Laser authorized per- sonal.
The intended effect of the laser application is based on the interaction of the radiation with the tissue components. The laser radiation is absorbed, scattered or reflected by the tissue. Air has only little influence on the C-LAS radiation and therefore the interaction between air and the C-LAS radiation can be neglected.

To avoid extended collateral damage (carbonisation and coagulation) at the cutting edges the application mode of the laser can be modified to a pulsed mode, which causes less damage. In continuous mode the laser permanently emits radiation. In pulse mode the tissue can cool down between each laser pulse and therefore the side effects of the heating can be reduced.
· excision of tissue (e. g. tumors) Technique The C-LAS laser is available with two different de- livery systems, the articulated arm and the flex- ible waveguide. For the articulated arm two differ- ent hand pieces are available, with 3 and 5 inch focal distance.
Alternative application in aesthetics and ENT The C-LAS laser is available with two different delivery systems, the articu- lated arm and the flexible waveguide. Furthermore, there is a scanner available that can be combined with the waveguide optics for ENT applications and is delivered with the articulated arm for dermatology and aesthetics applications.
With the UHP hand piece no aiming beam is available. To use the C-Las with waveguide, either hand pieces or an adapter or scanner hand piece are necessary to be connected to the waveguide optic. Direct application is possible via a radiation and small hand piece.
This means, that the user has to make sure that after the sterilization pro- cess there is enough time for the parts to dry out or actively dry the material. In case of water inside the insert, which may also result from water in the UHP while positioning the insert, the CO laser radiation may be blocked.
Pre-treatment tests The C-LAS laser does an automatic internal testing on the power output be- fore the device can be used. Keep an eye on the system components. Espe- cially take a look on the waveguide (waveguide version) and hand pieces: the spot shown by the aiming beam should always be round and defined, no scat- tering should occur (waveguide version only with focusing hand piece).
The user should not continue the use of the laser and contact his local A.R.C. Laser representative. When he checks the laser a restart results in a new check of the system at the beginning.
Treatment parameters Treatment parameters shown in this manual can only be an advice. The data is based on average values generated by our multiple C-Las users. Continuous mode causes more haemostasis and more extended collateral damage (higher effective power, faster, more efficient cutting), pulsed mode reduces collateral damage (less effective power, slower, less efficient cutting).
