…the laser becomes highly insensitive to vibration and thermal cycles. All Sapphire lasers are manufactured in controlled cleanrooms and hermetically sealed, before being run through rigorous testing procedures designed to keep variances from laser to laser to a minimum. This results into lasers with…

…beam quality, and for many years, these lasers were lamp-pumped. But the ever-increasing power and lifetime characteristics of laser diodes are causing these lasers to switch to diode pumping; i.e., DPSS lasers. Conversely, lower-power Q-switched DPSS lasers are often based on Nd:YVO4. These are…

…trivalent Nd ions, and are emerging as one of the most popular choices for gain elements used in diode pumped solid state lasers. Advantages of Vanadate over Nd:YAG Vanadate's broad absorption peak means that it can be pumped at high efficiency over a wide wavelength range. As a result, the laser
