DPAL Pump System Exceeding 3kW at 766nm and 30 GHz Bandwidth
Due to their low quantum defect, diode pumped alkali metal vapor lasers (DPALs) offer the promise of scalability to very high average power levels while maintaining excellent beam quality. Research on DPALs has progressed to ever increasing power levels across multiple gain media species over the last years, necessitating pump power in the kW range. Each material requires a specific pump wavelength: near 852nm for cesium, 780nm for rubidium, 766nm for potassium, and 670nm for lithium atoms. The...
Multi-kW High-Brightness Fiber Coupled Diode Laser Based on Two Dimensional Stacked Tailored Diode Bars
We have developed a scalable and modular diode laser architecture that fulfills these requirements through use of a simple beam shaping concept based on two dimensional stacking of tailored diode bars mounted on specially designed, tap water cooled...
Narrow-Line Fiber-Coupled Modules for DPAL Pumping
A new series of fiber coupled diode laser modules optimized for DPAL pumping is presented, featuring greater than 400W from a 600µm core fiber of 0.22NA. Addressing one of the key challenges in DPAL pumping, the modules achieve a spectral width of...
Narrow Line Diode Stacks for DPAL
Diode pumped alkali metal vapor lasers (DPALs) offer the promise of scalability to very high average power levels while maintaining excellent beam quality, making them an attractive candidate for future defense applications. A variety of gain media...
High-power Visible Spectrum Diode Lasers for Display and Medical Applications - Beam Sources with Tailored Beam Quality and Spectral Characteristics
Improved beam shaping concepts allow coupling of red and blue diode lasers into smaller fibers. For medical applications beam sources with narrow wavelength distribution in the blue spectral region were developed. Modules up to 100W in a 400µm...
