A diode laser is used in the light lever force sensor of the TT-AFM. The diode wavelength is 650 nm and it outputs 2 miliwatts of power. It requires a 5 volt power supply and has two 18” leads that can be directly inserted into the TT-AFM stage interface board. With regard to safety, the laser is Class II and should not be viewed directly for long time periods without the aid of filtered glasses.
