We have the capability to perform single or multi-beam nanosecond pulsed laser interference processing of materials. A spectra-Physics Injection seeded Lab-130-50 Nd:YAG laser with 4th harmonic (266 nm) is at the heart of this. Peak output power is 35 MW at 1064 nm and ~ 5 MW at 266 nm (44 mJ and 9 ns pulse width at 266 nm); repetition rate up to 50 Hz and a ~ 1 cm2 beam size; coherence length of ~ 2 m. The laser operation area is enclosed by a UV-absorbing 0.5” thick Plexiglas cover and further isolated from general work area by a sliding curtain. All users follow OSHA guidelines for class-1V laser operation, including eye examinations prior to beginning use of the laser and use of appropriate eye-wear. Ophir electronics PE30 A-P high-power laser detector head with ORION power meter for laser energy density measurements. Thorlabs PDA 155 Si amplified photodetector and DET210 high-speed photodetector for laser pulse width and time transient measurements. Various low-power He-Ne and solid state lasers with 535 or 633 nm wavelengths for optical reflectivity measurements and vibration monitoring. Polytec PI model E-610 piezoelectric motion controller and model P-841 closed loop piezo translator for active phase correction of optical interference system.Various high-power UV grade mirrors, beamsplitters, polarization rotator waveplates and lenses from Thorlabs or CVI optics for UV-laser control.
