Highly efficient, dynamically stable Nd : YAG single-rod resonators with 60% TEM00extraction efficiency and high misalignment stability

“…Stable laser operation requires a minimum amount of overlap between the radial and tangential stability intervals. As pointed out above, the stability zones get narrower when the mode radius increases and, therefore, the overlap between the radial and the tangential stability zones decreases until the operation in TEM 00 ceases [10]. To increase the size of the stability interval without decreasing the mode size, a resonator with joined stability zones can be designed [7,11,12].…”

AOM fourfold pass for efficient Q-switching and stable high peak power laser pulses

“…Particularly Nd:YAG lasers emitting in the near infrared around 1 lm are widespread and powerful laser sources [2,3]. Although diode pumping meanwhile is well established due to its efficient excitation, and lead to high power laser systems with excellent beam quality [4,5], the traditional transversely lamp pumped and water cooled Nd:YAG rod laser still has a big importance, because of its technological simplicity and robustness [6][7][8].…”

Aperture obstruction influences birefringence evaluation of a Nd : YAG laser system with tandem-set rods

“…Many new approaches and technical procedures have been proposed and implemented to reduce thermally induced effects for diode pumped solid state lasers (DPSSLs) since the early 1990s of the last century [1][2][3][4]. Among all thermal effects in a DPSSL, the thermally induced birefringence (TIB) is a knotty phenomenon in particular when the laser system suffers a high pump power [5][6][7].…”
