Abstract

Un interferometro y un método para medir las propiedades opticas de muestras en bloque. Se aplica un haz de láser sonda en dos brazos del aparato,un brazo de medicion, ambos contienen una fibra optica para conducir las luces de láser. El brazo de medicion incluye una zona de espacio libre para instalaruna muestra sometida a prueba. Se dirige el haz de sonda hacia la muestra en el espacio libre. La muestra también recibe luz en el espacio libre, en vez de víafibra optica, desde un segundoláser de bombeo. La interaccion de la muestra y el láser de bombeo afecta las propiedades opticas de la muestra. Este cambio enlas propiedades opticas puede detectarse al comparar las senales de salida desde los brazos de medicion y de referencia.An interferometer and a method to measure the optical properties of block samples. A laser beam probe is applied to two arms of the device, a measuring arm, both contain an optical fiber to drive the laser lights. The measuring arm includes a free space area to install a sample under test. The probe beam is directed towards the sample in the free space. The sample also receives light in the free space, instead of optical fiber, from a second laser pump. The interaction of the sample and the pumping laser affects the optical properties of the sample. This change in optical properties can be detected by comparing the output signals from the measurement and reference arms.
