Growth of organic crystal thin film by a new method-rectangular heater heated pedestal growth method
In the present investigation, to make a phase matched crystal for any wavelength, we report the growth of thin film of 2-adamantylamino-5-nitropyridine (AANP) from molten state by a new and simple technique namely rectangular heater heated pedestal growth method. Using this method crystal thin film has been grown along a, b, c-directions and along the phase matching direction at 1.55 mum wavelength (60degrees from c-axis towards b-axis). Temperature profile of the growth cell has been studied to confirm its stability. X-ray diffraction studies confirmed the direction in which the film has been grown. Second harmonic light from 1.55 mum laser was clearly detected just in plane of the crystal grown towards the phase matched angle of the wavelength.
