Laser display radiation source and method

摘要

In general, in one aspect, the invention features a method that includes converting radiation at a first wavelength lambda_i to radiation at a second wavelength lambda_g and exposing an article to the radiation at lambda_g to convert the radiation at lambda_g to radiation at a third wavelength lambda_r and radiation at a fourth wavelength lambda_b. lambda_r is red radiation, lambda_g is green radiation, and lambda_b is blue radiation and the article includes lithium tantalate.
