Abstract
Many studies are now underway to develop frequency conversion to obtain green or blue light for application to high-density optical memory. Organic materials are especially promising because of their very high, nonlinear-optical coefficients. Intracavity second-harmonic generation (SHG) in solid-state lasers pumped by a laser diode (LD) offers a simple method for obtaining shorter wavelength light with high conversion efficiency. We have grown a new organic crystal, Thienylchalcone, and have generated green light (532 nm) by the intracavity method using this crystal.
