    Explosion Warning This instrument must not be operated in an explosion endangered environment. Laser Warning The FSLOPAX1 laser is a Class IV laser. Avoid Eye or Skin Exposure to Direct or Scattered Radiation. Laser Warning Always wear appropriate laser safety eyewear during laser setup and operation.
  • Page 5 Class 4 lasers such as the FSLOPAX1 laser may cause damage to the skin, and also to the eye, even from the viewing of diffuse reflections. These hazards may also apply to indirect or non-specular reflections of the beam, even from apparently matte surfaces.

If using your own power cord, make sure it is IEC 320 compatible. 16. Make sure that the line voltage rating marked on the rear panel agrees with your local supply and that the appropriate fuses are installed.
  • Page 7 50 to 60 Hz. It draws 10 A maximum. The maximum power consumption is dependent on the operating parameters of the laser system, with a peak power draw of less than 400 W and a typical operational power draw of 100 W. The FSLOPAX1 chiller requires 100/240 VAC, 50/60 Hz, 5 A max. Laser Output Parameters The output parameters for the laser system are outlined in the table below, followed by classification warning labels, shown in Figure 3.

    LEDs. In the Simmer state the user can change the repetition rate of the pulse picker. The FSLOPAX1 OPA can provide either a 1035 nm or 1650 nm output beam, which are referred to as “Bypass” and “OPA” operation modes in the software GUI. Please note when operating in the Bypass mode the OPA output is disabled, and vice versa.
