355 nm Tailored Pulse Tandem Amplifier

Potential of sub-microsecond laser pulse shaping for controlling microcavitation in selective retinal therapies

“…The concept of pulse duration gives limited information about rates of laser energy deposition in tissues, such rates being actually determined by the pulse amplitude profile or shape. The recent advent of nanosecond and picosecond fiber lasers with flexible pulse formats [52][53][54][55][56][57] opens up new opportunities for improving control and precision in laser treatments involving microcavitation. Pulse shape tailoring can be used to finely adjust the rate of energy coupling in tissues and can, in principle, be tuned to generate ideal temperature fields allowing for a precise control of both heat diffusion and the kinetics of vaporization, thereby optimizing thermomechanical confinement.…”

303.5 nm cw Pr:BYF–BBO laser emission under 447 nm all-solid-state Nd:GdVO4–BiBO blue laser pumping

“…In the past 20 years, extensive efforts toward the development of nonlinear-optical crystals have been aimed at producing such a laser by means of frequency conversion of high-power solid-state lasers [10-12, 9, 13-17]. Most of the research on the UV radiation has been focused on pulse lasers [18][19][20][21][22][23][24][25][26]. Very little work about the continuous-wave (cw) UV radiation has been reported.…”

Diode-pumped Nd:GAB self-frequency-doubling green laser at 531 nm

“…Compact lasers that emit a few watts of green power are attractive for display, medical, and spectroscopic applications [11][12][13][14]. Such lasers could also become critical components of an allsolid-state compact UV source [15][16][17][18][19][20]. In recent years, rare earth ions doped nonlinear laser crystals such as Nd 3+ or Yb 3+ doped YAB, GCOB, YCOB, and MgO:LiNbO 3 have been paid much attention [21][22][23][24][25][26][27][28][29][30][31][32][33][34], because they combine laser and nonlinear optical functions into a single crystal, which makes it possible that the red, green, and blue lasers can be produced in a crystal via self-frequency-doubling of fundamental infrared lasers of the active ions and self-sum-frequency-mixing of fundamental and pump lasers.…”
