9 shows the temperature tuning characteristics of an LBO OPO pumped using a diode-pumped Nd: YLF laser [Ferguson (1994)]. 8. A resonant enhancement cavity for frequency doubling a Nd:YLF laser [after Ferguson (1994)]. temperatures in the range 400-440 K the OPO device will operate on four different wavelengths. However, at an operational temperature of 460-470 K the OPO works on a single frequency. The output is very stable and the threshold is only 70 mW. Varying the crystal temperature in the range 390 K to 470 K permits continuous tuning from 650nmto2900nm.

31)). Above threshold the population inversion ANt does not grow further: it is 'clamped' at ANt because of the rapidly increasing rate of stimulated emission that builds up in the cavity as the pump rate is increased above threshold. Cavity losses including the transmission (T) of the output coupler increase the threshold power above which the intensity of stimulated emission increases. The threshold power, P th , is where L is the passive cavity loss, hvp is the energy of the pump photons, the A are the cross sections of the pump (p) and laser (1) beams, ac is the cross section for stimulated emission, r is the luminescence life time and rjp is the pump efficiency.

The laser is end-pumped through one of the dielectric mirrors with an appropriate semiconductor diode array. A boule of Nd-YAG of length 200 mm and diameter 100 mm costing around $5000 is sliced into 200 wafers of thickness 500-750 |xm, which are polished, dielectrically coated and then cut into pieces with dimensions « l x l mm 2 . Each tiny crystal is a complete laser cavity and is potentially very cheap. These devices have quite amazing ranges of operational characteristics. They can be operated as tunable CW lasers or as ultrashort pulse lasers with high peak powers and large pulse repetition rates.
