1. SAFETY PRECAUTIONS
This section should be carefully reviewed prior to operating the ORPHEUS optical parametric
amplifier (OPA). Safety precautions contained herein and throughout the manual must be carefully
followed to ensure that all personnel who operate the laser and the OPA are protected from accidental
exposure to laser radiation and high voltage.
ORPHEUS, when coupled with an appropriate pump laser,
comprises a Class 4 laser product. Avoid eye or skin exposure
to direct or scattered radiation. It may cause skin injuries,
eye damage with possible blindness, and could also
constitute a fire hazard.
ORPHEUS, when coupled with an appropriate pump laser, comprises a Class 4 laser product that
poses safety hazards if not used properly. Produced direct or scattered radiation can cause permanent eye
damage and possible blindness, skin injuries. Beams can be powerful enough to burn skin, clothes, or ignite
fire and can also damage light sensitive optical equipment such as video cameras, photodiodes, etc. It is
imperative that users learn all safety information, which is provided in the pump laser’s manuals.
1.1 Optical Safety
Maximum accessible radiation level from the ORPHEUS. The used and emitted power/pulse energy
by ORPHEUS may vary upon the type and model of pump laser used. The average input power may be
20 W, with pulse duration ranging from 100 to 300 fs. Emitted radiation can be over 20 W, 2 mJ and 10-
300 fs pulse width. The wavelengths emitted by/present in ORPHEUS are: 1030 nm, 515 nm, 620-3000 nm.
Additional frequency mixers extend the tunable range to 210 nm to 20 µm. Be very careful when aligning
and working with ORPHEUS.
Avoid viewing the beam and specular reflections. Always
wear protective eyewear when aligning and operating the
ORPHEUS. Ensure your protective glasses cover all
wavelengths emitted by the laser system.
User is advised to follow the precautions below:
1. Always wear protective eyewear. Choose protective eyewear appropriate to wavelength and
intensity of the radiation, conditions of use, and visual function required. Remember that the
ORPHEUS output wavelength can be automatically and continuously tuned in broad wavelength
range.
2. Never look directly into the laser beam or scattered laser light from any reflective surface.
3. Avoid wearing watches, jewelry and other objects that may reflect or scatter the laser beam.
4. Set up the laser system so that laser beam paths are located well below eye level. Keep the
beams enclosed where possible.
5. Use energy absorbing targets and shields for beam blocking and preventing unnecessary
reflections or scatter.
6. Avoid blocking the laser beam or its reflection with any part of your body.
