Design of A Femtosecond Blue Pulse Generation System By Pumping Of Kn Crystal With Cr:LiSAF Lasers
Journal Title: International Journal of Fundamental Physical Sciences - Year 2013, Vol 3, Issue 2
Abstract
In this paper, we described and simulated the generation of blue pulse (460nm) by nonlinear KN(KNbO3) crystal, that pumped by femtosecond diode-pumped Cr:LiSAF lasers. Our simulation show that, by focusing of laser oscillator output pulses with characteristics such as 860nm wavelength, 200fs,330MHz repetition rate 14o Pico joule( PJ) energy in KN crystal with 3mm length at 22 0C by 15 mm lens in less than 20 micrometer spot size with single pass produce pulses with 42pJ energy ,425fs , 30% optical efficiency and 1% total efficiency.
