We report on stable, long-term operation of a diode-pumped solid-state laser (DPSSL) amplifying 15 ns pulses at 1029.5 nm wavelength to 10 J energy at 100 Hz pulse rate, corresponding to 1 kW average power, with 25.4% optical-to-optical efficiency.

- - The study assessed the Brazil Mood Scale (BRAMS) for screening mental health risks in athletes by analyzing responses from 898 participants across various sports, focusing on both current and past week mood evaluations.
- - Results showed that BRAMS effectively measures mood with reliable subscales, revealing that fatigue, depression, and tension were reported higher for the past week compared to right now.
- - Findings indicated gender differences in vigor levels (males higher than females) and age differences in anger and depression (younger athletes reported lower scores) but noted no significant differences related to social vulnerability status.
Article Synopsis
- Researchers successfully amplified 10 ns pulses up to 10 J energy at a rate of 10 Hz using a DiPOLE laser amplifier with innovative Yb:YAG/Cr:YAG composite slabs made via adhesive-free bonding (AFB) technology.
- The bonded slabs demonstrate effective performance in high energy cryogenic laser amplifiers and allow for efficient frequency doubling, achieving 3.9 J in the green spectrum from a 5 J infrared output with a 78% conversion efficiency.
- The study highlights AFB technology’s potential to produce larger gain material slabs, addressing current manufacturing limits and facilitating energy scaling in high-energy lasers where traditional methods fall short.*
We report on obtaining output energy of 146 J in 10 ns long pulses at 10 Hz repetition rate from Bivoj, a multi-Joule multi-slab cryogenic gas-cooled diode pumped solid state laser, by overcoming its damage threshold bottleneck. This is a 40% energy and power increase of the laser system in comparison to our previous publication and to the most powerful multi-Joule high power laser system.

We demonstrated generation of 59.7 J at 10 Hz (597 W) at 515 nm (second harmonic) and of 65.
