An end-pumped laser scheme using diode-laser stack and additive shaping optics has been implemented. The improvement of laser output power and efficiency of high power diode-end-pumped laser using composite YAG/Nd:YAG/YAG rod instead of simple Nd:YAG rod has been investigated experimentally. Compared to the simple rod laser, the output power and efficiency of the composite rod laser were increased more than 80% and 21.5% respectively, with a more homogenized beam profile. Also the laser threshold was decreased 90% in the composite rod. These results are due to the decrease of thermal effects..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
