Jei-Pico laser, originally developed by Jeisys Medical in Korea, uses a new electro-optics technology beyond the existing SBS and Microchip laser. The characteristic feature of Jei-Pico is the variable pulse width from 180 ps to 2000 ps. Another function of Jei-Pico laser is that it’s capable of 15 bundle pulses in one pumping cycle. Jei-Pico is capable of pulse combination that can change the pulse width of each of the 15 bundle pulses. The seed laser has been made with electro-optics technology that has a gain factor of ~9.0 × 109 through three optical amplifiers. The development of Jei-Pico is focused on Nd:YAG rod with 1064 and 532 nm. Maybe this technology can be applied to 532 nm as a pumping source to the Ti:Sapphire or alexandrite rod to produce the 700 nm~ wavelength. Jei-Pico has about 600 MW for 1064 nm and 220 MW for 532 nm.
