Stress-induced birefringence in a single-transverse-mode YAG laser is well compensated simply by having the end mirror one Rayleigh range away from the gain.
We report on the development of a sub-mJ Ti:sapphire laser operating at 50 kHz. Downchirped-pulse amplification chain, including 2 amplifiers pumped by one green laser, allows the generation of multi-GW femtosecond laser pulses.
We report a tunable laser source emitting in the visible (530 nm, 630 nm) and the near infrared (775 nm, 1060 nm, and 1550 nm) regions by frequency summation of a dual wavelength Er/Yb co-doped fiber laser.
We demonstrated harmonic mode locking in nonlinear mirror mode-locked Nd:GdVO4 laser. In normal dispersion, fourth harmonic mode locking can be generated rate by changing the distance between the nonlinear crystal and output coupler mirror.
Laser emission near 780 nm with 2 mW output power and 3.3% slope efficiency from a Ti:sapphire buried channel waveguide is demonstrated. The sample was fabricated by proton implantation.
We demonstrate for the first time Q-switched and mode-locked laser operation of the Li6Y(BO3)3:Yb3+ crystal. Up to 140 muJ pulse energy and down to 355 fs pulse duration were achieved.
A novel resonator concept that produces axisymmetric output from a thin-planar gain medium with a highly elliptical pump cross-section is described. Preliminary studies of this power-scalable approach using a Nd:YLF slab laser are presented.
We study the power dependence of the back reflection from microsphere resonators. Experimental results are compared with theoretical models. An EDFA (Erbium Doped Fiber Amplifier) based laser with a microsphere mirror is demonstrated.
