Developed a 2.6J/pulse Q-switched Nd:YAG Laser with flat-top beam profile for Thermolase Softlight Hair Removal Process. Patentable device incorporated a proprietary beam-delivery system, allowing for 50% increase in efficacy for patients with wide range of skin color. The laser was CE Marked, approved for sale in the U.S., Japan and Korea and resulted in $25M in revenue. Developed a high-energy (3.3 J/pulse, 10 Hz, 110VAC) and the most efficient at the time Er:YAG laser for Naturalase Skin Resurfacing Process. Device incorporated a novel fully-automatic, motorized handpiece with auto-adjustment of the spot-size and output energy for a given fluencePerformed design analysis and initial experiments on generation of 585 nm out of a dual-wavelength LP Nd:YAG laser through frequency-mixing; carried out efficacy assessment of a variable-pulsewidth diode-pumped Er:YSGG laser for skin resurfacing with both ablation and coagulation capabilities. Performed numerous Marketing and R&D presentations for medical doctors, prospective clients, investors and business alliances.

Developed a second-generation, higher power Medlight Q-switched Nd:YAG laser (1064/532 nm) for the removal of tattoos and treatment of pigmented lesions. Developed an original fluoride fiber-based beam delivery arrangement for the Er:YAG laser for hard-tissue dental applications (in collaboration with Hoya Ltd., Japan). The assembly included sealed quartz jacket, purged by a N2-generator. Carried out the experiments on using this fluoride-fiber as a delivery system of a high-energy Er:YAG laser for skin resurfacing. Achieved safe coupling of 2+ Joule/pulse with >85%/m efficiency. Performed design work of the 585 and 650 nm Polymer Dye handpieces for the Medlight-series Nd:YAG Laser. Efficiencies in excess of 60% had been demonstrated with input energies of up to 800 mJ/pulse/532 nm.

Developed a pulsed Nd;YAG laser for welding metals and alloys used in dental restoration industry; designed proprietary beam delivery and imagining arrangements for the remote welding.Conducted a full-cycle product development from a conceptual design to the release into production of a 100Hz Nd:YAG and 30Hz Cr, Tm, Ho:YAG combo-laser for the soft-tissue dental applications.Designed a novel laser beam attenuator for surgical system. The unit allowed very rapid and continuous output power adjustment with minimal spatial beam quality distortion with dynamic range of 40 dB and average power of up to 100 W.Performed experimental work on KrF excimer laser etching and repair of phase-shifting semiconductor photomasks. Wrote technical proposal and won a defense contract for an all Solid-State Laser simultaneously emitting three primary RGB colors. The system was based on a dual Ti:Sapphire laser, pumped by a frequency-doubled, high repetition rate diode-pumped Nd:YLF laser. This patented device was first of its kind used for color separation in high-resolution printing.
