Treatment of aneurysms and other neurological conditions would benefit from improved guidance of wires in arteries and the resulting reduction in time required to insert catheters and other imaging or treatment devices. By making a small opening in a

We report on measurements of beam profiles of near-infrared idler pulses from an optical parametric oscillator (OPO) using an infrared (IR) camera for wavelengths ranging from 1850 nm to 2050 nm, wavelengths of particular interest for optical pumping

We report on an experimental investigation of the time-dependent spatial intensity distribution of near-infrared idler pulses from an optical parametric oscillator measured using an infrared (IR) camera, in contrast to beam profiles obtained using tr

Type-II W optical pumping injection cavity lasers emitting ~3 μm at room temperature are pumped resonantly by tuning with an optical parametric oscillator. The resonance pump wavelength consistently is found to vary quadratically with temperature. L

An optical parametric oscillator is tuned to the resonance wavelength of the etalon in an optical pumping injection cavity (OPIC) laser with a type-II “W” active region, thereby minimizing the threshold pump intensity and maximizing the output sl

A series of optically pumped type-II quantum-well “W” lasers with wavelengths ranging from 5.4 to 7.3 μm operated at temperatures up to at least 220 K for pulsed operation. The peak output power at 80 K was 1.1 W/facet for a device emitting at

The heat-sinking properties of optically pumped semiconductor lasers mounted by the diamond-pressure-bonding (DPB) technique have been evaluated quantitatively. This method combines epi-side-down mounting with minimal processing and top optical acces

The authors review recent demonstrations of improved mid-IR laser performance when a type II ‘W-well’ structure is incorporated into the active region. The W configuration consists of a hole quantum well (e.g. GaSb or GaInSb) between electron qua

While conventional semiconductor lasers employ electrical injection for carrier excitation, optically pumped semiconductor lasers (OPSLs) have demonstrated high output powers and high brightness in the mid-infrared. An important consideration for opt
