Autor: Takayuki Yanagisawa, Shumpei Kameyama, Kenichi Hirosawa, Narito Samejima, Kenichi Uto, Takeshi Sakimura
Publikováno v: Laser Congress 2019 (ASSL, LAC, LS&C).
We have demonstrated high-energy amplification of sub-nanosecond laser pulses with an Er,Yb:glass planar waveguide amplifier. The output pulse energy reached 500 μJ at 20 kHz repetition rate, 500 ps duration, and 1534 nm wavelength.

7.4 mJ laser amplifier at 1531.4 nm for water vapor differential absorption lidar (DIAL)
Autor: Kenichi Hirosawa, Shumpei Kameyama, Takayuki Yanagisawa, Takeshi Sakimura
Publikováno v: Laser Congress 2017 (ASSL, LAC).
We developed high energy laser amplifier for a water vapor differential absorption lidar. The amplifier was based on a planar waveguide with Er, Yb co-doped glass, and achieved 7.4 mJ pulse energy at 1531.4 nm

Publikováno v: SPIE Proceedings.
We have developed a 1.5-μm eye-safe wavelength high average power laser amplifier using an Er,Yb:glass planar waveguide for coherent Doppler LIDAR. Large cooling surface of the planar waveguide enabled high average power pumping for Er,Yb:glass whic

Wind sensing demonstration of more than 30km measurable range with a 1.5μm coherent Doppler lidar which has the laser amplifier using Er,Yb:glass planar waveguide
Autor: Toshiyuki Ando, Hisamichi Tanaka, Takayuki Yanagisawa, Yojiro Watanabe, Shumpei Kameyama, Kimio Asaka, Hamaki Inokuchi, Yoshihito Hirano, Takeshi Sakimura
Publikováno v: SPIE Proceedings.
Recently, we have developed the high output power laser amplifier using Er,Yb:glass planar waveguide in order to increase the measurable range of our 1.5 μm coherent Doppler LIDAR (CDL). In this paper, we introduce this development and demonstration

1.5-μm high-gain and high-power laser amplifier using a Er, Yb:glass planar waveguide for coherent Doppler LIDAR
Autor: Takayuki Yanagisawa, Shumpei Kameyama, Toshiyuki Ando, Yojiro Watanabe, Hamaki Inokuchi, Kimio Asaka, Hisamichi Tanaka, Yoshihito Hirano, Takeshi Sakimura
Publikováno v: Conference on Lasers and Electro-Optics 2012.
We have developed a 1.5-μm high-power laser amplifier using Er, Yb:glass planar waveguide for a coherent Doppler LIDAR. Large cooling surface of the waveguide realized highaverage power pumping for Er, Yb:glass which has low thermal fracture limit.
