In this Letter, we report on the development of an ultra-compact single-frequency Ti:sapphire laser under direct diode pumping. Single-longitudinal-mode operation is realized from a miniature plane-parallel resonator using a volume Bragg grating as a

For many years, Ti:sapphire was the prototypical example of a solid-state laser material that could not be diode pumped. The rationale for this assessment follows from the laser properties of Ti:sapphire, which combine to demand high brightness pumpi

To date, demonstrated ultrashort pulse seed sources for Ho3+-doped amplifiers, such as Ho:YAG and Ho:YLF, leave a lot to be desired in terms of complexity, cost, and efficiency. Sources like those used in [1] involve nonlinear energy transfer schemes

We present an amplifier system for 2 µm ultrafast laser pulses for potential material processing applications. The amplifier gain material is a 0.75 at.% doped Ho:YAG slab crystal measuring 10 mm x 1.5 mm x 55 mm. The pump source is an in-house deve

The development of efficient, low-cost and robust high peak power pulsed lasers in the ~ 2 – 2.1 µm spectral region is required for many application areas in the mid-infrared (mid-IR) photonics sector. In particular, such laser sources can be used

In this paper we present on-chip mode-locked waveguide lasers fabricated in Yb-doped phosphate glass and Er, Ybdoped phosphate glass. At 1 micron wavelength, pulse repetition rates of up to 15 GHz with pulses ~800 fs were demonstrated and at 1.5 micr

We report a broadly wavelength-tunable femtosecond diode-pumped Ti:sapphire laser, passively mode-locked using both semiconductor saturable absorber mirror (SESAM) and Kerr-lens mode-locking (KLM) techniques. Using two pump laser diodes (operating at

We report on the first demonstration, to the best of our knowledge, of a diode-pumped Tm:LuScO3 laser. Efficient and broadly tunable continuous wave operation in the 1973-2141 nm region and femtosecond mode-locking through the use of an ion-implanted
