He is the author of several textbooks on laser spectroscopy and a series of four textbooks on experimental physics. His books entitled Laserspektroskopie [1] and Laser Spectroscopy [2] [3] are considered classics in the field. From 1970 til 1999, he was ordinary professor at Kaiserslautern University of Technology. [4]
Alternatively, if a stable laser is available, the PDH technique can be used to stabilize and/or measure the instabilities in an optical cavity length. [3] The PDH technique responds to the frequency of laser emission independently of intensity, which is significant because many other methods that control laser frequency, such as a side-of ...
Ultrafast laser spectroscopy is a category of spectroscopic techniques using ultrashort pulse lasers for the study of dynamics on extremely short time scales (attoseconds to nanoseconds). Different methods are used to examine the dynamics of charge carriers, atoms, and molecules.
The laser produces a tiny, intense spot on the screen to the right. The center of the spot appears white because the image is overexposed there. Spectrum of a helium–neon laser. The actual bandwidth is much narrower than shown; the spectrum is limited by the measuring apparatus.

Laser-induced fluorescence (LIF) or laser-stimulated fluorescence (LSF) [1] is a spectroscopic method in which an atom or molecule is excited to a higher energy level by the absorption of laser light followed by spontaneous emission of light. [2] [3] It was first reported by Zare and coworkers in 1968. [4] [5]
Laser science or laser physics is a branch of optics that describes the theory and practice of lasers. [ 1 ] Laser science is principally concerned with quantum electronics , laser construction , optical cavity design, the physics of producing a population inversion in laser media , and the temporal evolution of the light field in the laser.
F-center laser 2.3-3.3 μm Ion laser Spectroscopy Optically pumped semiconductor laser 920 nm-1.35 μm Laser diode Projection, life sciences, forensic analysis, spectroscopy, eye surgery, laser light shows. The lasing medium is a semiconductor chip. Frequency doubling or tripling is typically done to produce visible or ultraviolet radiation.
