Abstract
We demonstrate a method for the excitation of Hermite Gaussian modes ( one transverse dimension) in end-pumped solid-state lasers. The excita tion is performed by pumping off-axis with the help of a fibre-coupled laser diode. With increasing transverse separation of the fibre from the optical axis, the Hermite Gaussian modes can be successively obser ved. This laser has a variable M(2)-factor and can therefore be used a s an M(2)-standard in calibration purposes. M(2)-factors between 1 and 190 are attained with this method.
