“…Consequently, "diode-pumped dye laser" reports have emerged in the recent literature. [7][8][9] It is worth noticing that albeit these reports have dealt with traditional laser dyes (rhodamines, coumarins, pyrromethenes…), the concept is also transferrable to novel solution-processable gain materials, e.g. soluble organic semiconductors or colloidal quantum dots.…”

“…soluble organic semiconductors or colloidal quantum dots. 10 Diode-pumped liquid dye lasers have been demonstrated with both circulating 11,12 and noncirculating [7][8][9] dye solutions.

A highly stable diode-pumped circulation-free liquid dye laser in a vertical external cavity is reported. The design is simple (no fabrication process step required, no fluid circuitry), compact (~ cm sized), and cost-effective. An optical efficiency of 18% with a M² of 1 are reported, with an excellent photostability -no efficiency drop was seen after 1.4 million pulses at 50 Hz, a value comparable to flowing systems and much higher than values achievable with organic solid-state lasers. We show that thermal effects are central in the stability and also on the dynamics of this laser. The laser build-up and shutdown dynamics are studied in detail for different pump pulse durations/repetition rates; they reveal a pulse shortening with increasing pump pulse duration and repetition rate that are shown to be due to thermal lensing diffraction losses. This laser structure offers a very convenient and simple platform for testing or harvesting solution-processable gain materials.

“…Nevertheless, the peak power of laser diodes is weak compared to the values achieved with pulsed femtosecond lasers, the threshold of polymer laser resonators should be as low as possible. Recently, diode laser pumped polymer lasers have been achieved up to now through the use of a few resonators, such as distributed feedback (DFB) [24][25][26], vertical cavity surface emitting polymer laser (VCSEL) resonators [27], and astigmatismcompensated three-mirror cavity [28,29]. The WGM microcavity lasers are widely used for sensing because of their high Q factor and low threshold [30][31][32][33].…”

Tunable whispering-gallery-mode (WGM) lasers have been paid lots of attention for their potential applications in the photonic field. Here, a tunable polymer WGM laser based on laser diode pumping is realized with a threshold of 0.43 MW/cm2 per pulse. The WGM laser is realized by a microfluidic microcavity, which consists of a quartz capillary and gain materials. The laser performance keeps stable for a long time (3.5 h), pumped by a 50-ns 50 Hz laser diode with a pumping peak power density of 1.08 MW/cm2 per pulse. The lasing wavelength can be tuned over 15 nm by changing the gain material concentration from 3.5 mg/mL to 12.5 mg/mL in the microfluidic channel. Moreover, the lasing mode can be switched between transverse magnetic (TM) and transverse electric (TE) modes by adjusting the pump polarization. These results provide the basis for designing nanophotonic devices with laser diode pumping.

“…2 Because they exhibit large absorption bands in the blue-green region of the spectrum, dye lasers are also well adapted for GaN diode-pumping and might follow the same route. [3][4][5][6][7][8] However, while liquid dye lasers have been the first tunable lasers, useful for e.g. spectroscopy, 9 medicine, 10 or sensing, 11 they are nowadays more confidential, mostly because of a painful and complex handling of dye solution circuitry.…”

Liquid dye lasers have long been considered as ideal tunable laser sources in the visible range but are bulky, expensive, and require a complex system for dye circulation. Here, we present a system that relies on a low-cost blue laser diode as the pump source and a sealed dye cell with no flowing circuitry, resulting in a device that combines the convenience and size of a solid-state device with the stability of a liquid organic laser. A very high photo-stability is obtained (up to 1.2 × 109 pulses or 12 days at 1 kHz), which is five orders of magnitude higher than a solid-state dye laser operated in similar conditions. The number of pulses obtainable at low repetition rates is found to be limited by molecular self-diffusion and, hence, related to the total cuvette volume. In contrast, the repetition rate is limited to a few kHz, which suggests that thermal effects play a bigger role than triplet population effects. Thermal effects participate in the suppression of lasing through the buildup of a strong negative thermal lens; correcting the non-aberrant part of this thermal lens by resonator design enables the repetition rate to be pushed up to 14 kHz with possible further optimization. This work shows a route for building off-the-shelf, compact, low-cost, and convenient tunable pulsed lasers in the visible range that have superior stability over organic solid-state lasers.
