Spectral phase retrieval of 8 fs optical pulses at 600 nm by using a collinear autocorrelator with 300-μm-thick lithium triborate crystals.

We report on noniterative spectral phase retrieval of 1.1 nJ, 8 fs pulses at 600 nm by using 300-μm-thick lithium triborate crystals in a standard collinear autocorrelator with ≈2 min data acquisition time. This method is simple, sensitive, and immune to the spectral distortion and UV absorption of the linear and nonlinear optics.

Observation of optical vortex streets in walking second-harmonic generation.

We report what is believed to be the first experimental observation of spontaneous nucleation of arrays of optical vortices in the process of second-harmonic generation in a crystal with moderate Poynting vector walk-off, pumped with focused beams containing screw phase dislocations. Our experiments were conducted in lithium triborate under conditions of small-efficiency second-harmonic generat...

Multiple-color cw visible lasers by frequency sum-mixing in a cascading Raman fiber laser.

Multiple cw visible lasers at wavelengths ranging from 550nm to 625nm were generated by intracavity frequency sum-mixing of a cascading Raman fiber laser in a type-I noncritically phase-matched lithium triborate crystal. The phase matching conditions for individual wavelengths were realized by tuning the temperature of the lithium triborate crystal.

Lithium Triborate-Laser Vaporisation of the Prostate using the 120W High Performance System (HPS) Greenlight-Laser: High Performance all the Way?

Despite technical refinements of the 120 W lithium-triborate laser fiber degradation and significantly decreased power output are still detectable during the procedure. Laser fibers are not fully appropriate for the high power delivery of the new system. There is still potential for further improvement in the laser performance. Lithium Triborate-Laser Vaporisation of the Prostate using the 120W...
