Description
Es zeigen
Bei einem in der vorstehend beschriebenen Weise ausgebildeten Festkörperlaser sind die Lichtquelle 4 und der mit der rauhen Oberfläche versehene Laserstab 300 im Brennpunkt einer Kavität 6 angeordnet, die im Schnitt elliptisch ausgebildet ist. Die Lichtquelle 4 wird über die Stromquelle 5 zur Abgabe von Licht eingeschaltet, und der Laserstab 300 wird mit dem abgegebenen Licht angestrahlt. Somit wird der Laserstab durch das abgegebene Licht angeregt.
