Considering laser medium thermal lens effect and thermal focal length changes with pumping power  conventionally  lasers are designed to operate in the middle of thermal stable zones  where the fundamental mode size is insensitive to thermal perturbation  while this method seems impossible when large fundamental mode size is required. Through self-select mode cavity  lasers are designed to work at the border of stable zone instead  where large fundamental mode size in gain media can be reached. With increase of pumping power and self-aperture mode-selective effect  mode size would grow up automatically to a certain value suitable for monomode resonance. With double 180 W pump modules  acoustic Q-switch and LBO external frequency-doubled  over 28 W which M2 equals 4.5 quasi-CW output green laser and 52W 1.064 um IR output is obtained simultaneity. With the insertion or not of the harmonic separator by footswitch  high beam quality green  IR  and green IR lasers are obtained conveniently.

We study insertion losses of optical switch when the laser beam is propagating during the free space between two single mode fibers (SMFs) and the related assemblage challenges  Then a new packaging structure is developed for the hybrid-integration of free-space MOEMS (micro-opto-electro-mechanical systems) chip with a silicon micromachined submount to improve alignment accuracy. The submount is designed to accommodate various free-space MOEMS chips with minimal active optical alignment  thus reducing the packaging cost. The silicon submount has a central recess to place the MOEMS chip in  sixteen V-grooves for optical fibers  and micropits for micro ball lenses  all bulk micromachined at the same time by a single anisotropic wet etching step. A corner compensation technique is employed to prevent erosion of the convex corners  where different geometries meet. Through this assembling method  the fiber  micro ball lens can be aligned preciously thus reduced lateral and angular misalignment between them. Then total insertion losses can be decreased.
