“…4, No. 7 (2007) cylindrical lenses (CL1 and CL2) both with focal lengths of 50 mm were inserted into the cavity for mode-matching in the y-axis direction [17]. An acousto-optics Q-switch was inserted between the laser crystal and the CL2.…”

Up to 1 MHz acousto-optics Q-switching operation was obtained in a grazing-incidence Nd:YVO4 laser. At 500 kHz repetition rate, 17.7 W of output power was obtained with 38 W of pump power when 32.4% transmissivity output coupler was used. The beam quality factors were measured as M 2 x < 4 in the x-axis direction and M 2 y < 2 in the y-axis direction. For high sable acousto-optics pulse operation, 5% transmissivity output coupler was used and 9.15 W of output power was obtained at 38 W of pump power. The peak-to-peak instability of pulse amplitude was less than ±3.3% at 489.6 kHz repetition rate.Photograph of oscilloscope traces showing the pulse series at 489.6 kHz

“…The controlled gain competition between the two near-parallel beams inside the slab guarantees stable TEM 00 mode operation at high pump powers, without inserting additional losses [15,16]. No cylindrical intracavity optics is needed to create the highly elliptical beams necessary with other techniques [14].…”

“…The main drawback of this architecture is its noncolinearity between pump and emission, which usually results in incomplete pump overlap and multimode operation [13]. One exception to the usually low efficiency in side-pumped lasers is an architecture based on gain media with high absorption cross section, such as Nd:YVO4 and Nd:GdVO4, where the shallow region of pump-induced inversion gets efficiently screened by a single-grazing incidence beam that undergoes total internal reflection (TIR) at the pump surface [14].…”

This work demonstrates the power scalability of double-beam-mode controlling, a technique that has generated the highest optical efficiency reported so far for Nd:YLF lasers. We analyze two types of power scaling possibilities by numerical simulations: multiplication of intracavity pump modules and MOPA configuration. About 44 W of TEM 00 output power at 1053 nm was experimentally demonstrated with a beam-parameter product of 1.07 9 1.15. The results show great ease of power scaling without sacrificing beam quality.
