Performance Evaluation of a Q-switched Nd: YAG-Laser Operating at the Fundamental ModeA performance test for a Q-switched Nd:YAG laser is proposed using a thin film of a substance that is readily attacked by the laser beam on a substrate that is not. The focused laser beam writes a track along the test plate which is tilted such that also burn marks are obtained from the defocused laser beam, see figure 1.

Tunable Wavelength Selective Semiconductor Laser Systems low as 15 kHz can be obtained in external cavity systems [5] well suited for coherent optical communication. In the following, we present some properties of very simple hybrid coupled-cavity and external cavity semiconductor lasers.

Untersuchung des thermischen Verhaltens und der Strahlqualit?t eines Nd-Glas Slab Lasersxgradienten und mechanische Spannungen. Bei herk?mmlichen Festk?rperlasern deren aktives Medium die Form eines zylindrisehen Stabes hat, führt dies zu einer Beeintr?chtigung der Laserstrahl-Qualit?t sowie zu einer Begrenzung der Laserausgangsleistung /1—3/.
