1. Laser device and method for ablating biological tissue

2. Optically pumped solid state laser device with self aligning pump optics and enhanced gain

3. Discharge starting voltage and holding current supply unit, and skin treatment multi-wavelength laser device including same

4. A double laser device of high stability was used to determinate the threshold bandwidth of a He/Ne-laser amplifier and oscillator.

5. The ablation depth of each of the test ablations is measured and an associated desired pulse energy is subsequently determined on the basis of the measured ablation depths and a predefined desired ablation depth and is set on the laser device.
