Welcome to visit us at SPIE Photonics West 2017

Time : 2017-01-18
It is that time of year again! BWT will be exhibition at Bios, January 28th-29th, and Photonics West, January 31st-February 2nd, at the Moscone Center in San Francisco.Welcome to visit BWT at booth #8816 at BIOS, and at booth #838 at Photonics West.
Not only those products you familiar with, we will release several new products at Photonics West.
The NewBeamTM Series fiber-coupled diode pump module offers up to 210 W output power from a 135μm fiber. The new platform design enables high brightness and cost-effective package. The NewBeamTM Series is a unique solution for fiber and solid-state laser pumping.

Paper 10086-1600W high brightness diode laser pumping source 
Presenter: Lei Xu
Abstract: Using spatial beam combination and polarization beam combination, BWT Beijing has achieved more than 650W output from a fiber with NA 0.22 and core diameter of 200μm. Multiple emitters with wavelength of 976nm are packaged in a module of size 180×150×70 mm3.  At 650W, fiber coupling efficiency reaches 94%, and electro-optical efficiency is higher than 49%. Steady state propagation of electromagnetic wave in free space is also simulated.
