High-power and highly efficient composite laser with an anti-reflection coated layer between a laser crystal and a diamond heat spreader fabricated by room-temperature bonding

Autor: Hiromasa Ichikawa, Tomo Katsumata, Kohki Yamaguchi, Ichiro Shoji

Publikováno v: Optics express. 25(19)

We have succeeded in bonding a Nd:YAG crystal and an anti-reflection coated diamond crystal to realize a composite laser which minimizes the Fresnel-reflection loss at the bonded interface for the first time. This newly developed composite laser has

Room-temperature-bonded Nd:YAG/diamond composite laser with an anti-reflection coating layer at the bonded interface for high-power and highly efficient oscillation

Autor: Ichiro Shoji, Hiromasa Ichikawa, Tomo Katsumata

Publikováno v: 2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC).

Thermal effects such as thermal lens and thermally induced birefringence are sources of degrading the beam quality and preventing higher-power operations in solid-state lasers. The composite lasers, which consist of laser-ion-doped and undoped materi

Successful Fabrication of a Nd:YAG/diamond Composite Structure with an Anti-reflection Coating Layer at the Bonded Interface for Highly Efficient Laser Oscillation

Autor: Yohei Okuyama, Ichiro Shoji, Hiromasa Ichikawa

Publikováno v: Lasers Congress 2016 (ASSL, LSC, LAC).

We have successfully fabricated a Nd:YAG/diamond composite structure with an anti-reflection coating layer to suppress Fresnel loss at the bonded interface by using the room-temperature-bonding technique. Higher-power and highly efficient laser oscil

Laser Characteristics of Nd:YAG/diamond and Nd:YVO4/diamond Composite Devices Fabricated with the Room-temperature-bonding Technique

Autor: Yohei Okuyama, Ichiro Shoji, Tomomi Onda, Yoshimi Ariga, Hiromasa Ichikawa

Publikováno v: Advanced Solid State Lasers.

We have developed Nd:YAG/diamond and Nd:YVO4/diamond composites using the room-temperature-bonding technique. Higher-power operation at higher pump power is possible for the composites than for non-composites, in spite of the Fresnel loss at the bond
