Diode Pumped Amplifier

- March 06, 2018

Dpssls have advantages in compactness and efficiency over other types and high power dpssls have replaced ion lasers and flashlamp pumped lasers in many scientific applications and are now appearing commonly in green and other color laser pointers. So when the laser diode pumps the erbium ions with a 980 nm photons the electrons in the ground state e 1 absorbs sufficient energy and jumps into the excited state e 3.

1 fully diode pumped ultrafast tisapphire oscillator amplifier system.

Diode pumped amplifier. The flexible system design allows a selection of different power and energy levels. Nevertheless these obstacles can be overcome. Thus the ideal ultrafast laserdiode pumped simple reliable and with uncompromising performancehas now been realized.

We investigate the average power scaling of two diode pumped yb doped fiber amplifiers emitting a diffraction limited beam. The first fiber under investigation with a core diameter of 30 x00b5m was able to amplify a 10 w narrow linewidth seed laser up to 28 kw average output power before the onset of transverse mode instabilities tmi. The useful small signal gain has been found to be limited by amplified spontaneous emission.

Systems designers should consider cw diode pumped systems instead of pulsed pumped systems for cost and reliability reasons. Here we report on a direct diode pumped tisapphire ultrafast regenerative amplifier laser system producing multi uj energies with repetition rate from 50 to 250 khz. Ddpts oscillators commercial tisapphire laser oscillators have in the past employed a number of pump laser sources including argon ion intra cavity doubled ndyvo4 frequency doubled opsels and doubled ir laser diodes.

Cw pumped q switched systems can efficiently drive nonlinear optics to generate tunable vis uv and ir wavelengths. Fiber amplifiers use an optical fiber as the gain medium and are typically set for specific requirements. By combining cryogenic cooling of tisapphire with high brightness fiber coupled 450nm laser diodes we for the first time demonstrate a power scalable cw pumped.

Dpss amplifiers are diode pumped solid state amplifiers use for a wide variety of applications. Edfa pumped with 980 nm laser diode the 980 nm wavelength photons have more energy than the 1480 nm wavelength photons. In this work we present what we believe is the first direct diode pumped tisapphire oscillatoramplifier system.

Modelocked tisapphire oscillator is pumped with 520nm diodes 17w while the amplifier is pumped by high power fiber coupled 450 nm diodes up to 100w and is cryogenically cooled. Diode pumped solid state lasers are solid state lasers made by pumping a solid gain medium for example a ruby or a neodymium doped yag crystal with a laser diode. The kerr lens modelocked tisapphire oscillator is pumped with 520nm diodes 17w while the amplifier is pumped by high power fiber coupled 450 nm diodes up to 100w and is cryogenically cooled.

Single pass small signal gains of up to 400 in 1 cm have been measured for the amplification of a ndyag probe beam in a simple diode side pumped ndyvo 4 slab amplifier using a single grazing incidence reflection.
