Product Description

Introduction

Holmium, Chromium, Thulium Co-doped Yttrium Aluminum Garnet (Ho:Cr:Tm:YAG) is a high efficient laser material which lases at 2.1 µm. It has wide applications in surgery, dentistry, atmospheric testing, etc. It is suitable for lamp pumping and can also be pumped by a laser diode, and the crystal has the advantages of high slope efficiency, room temperature operation, and a laser operating wavelength that is relatively safe for the human eye.

      •   High slope efficiency
      •   Pumped by flash lamp or diode
      •   Operates well at room temperature
      •   Operates in a relatively eye-safe wavelength range
