Laser-Induced Damage Threshold of Single Crystal ZnGeP2 at 2.1 μm: The Effect of Crystal Lattice Quality at Various Pulse Widths and Repetition Rates

Nikolai Yudin et al.

Summary: This paper presents the experimental analysis of the optical damage threshold of ZnGeP2 nonlinear crystals, and investigates the factors affecting the threshold. The results show that a reduced dislocation density of the crystal lattice is the main factor for higher damage threshold.

161 W middle infrared ZnGeP2 MOPA system pumped by 300 W-class Ho:YAG MOPA system

Gaoyou Liu et al.

Summary: A high-power switched two-stage Ho:YAG MOPA system was demonstrated using Tm:YLF lasers. A new method was introduced to improve beam quality by rotating and swapping spatial axial directions of pump beams. High power output was achieved by employing two parallel second-stage Ho:YAG amplifiers. Additionally, a ZnGeP2 MOPA system was demonstrated using the Ho:YAG MOPA as the pump source, achieving high power output with good beam quality.

Electro-optic active Q-switched Tm:YLF laser based on polarization modulation

Salman Noach et al.

Summary: An active Q-switched Tm:YLF laser with a unique switching scheme utilizing a potassium lithium tantalate niobate crystal has been developed. This novel approach effectively reduces oscillation effects and allows for stable pulse output with shorter pulse durations and higher energy at different repetition rates. The laser system demonstrates improved performance in generating pulses at 5 kHz and 500 Hz repetition rates.
